1 An Introduction to Word classes

Words are fundamental units in every sentence, so we will begin by looking at these. Consider the words in the following sentence:

my brother drives a big car
We can tell almost instinctively that brother and car are the same type of word, and also that brother and drives are different types of words. By this we mean that brother and car belong to the same word class. Similarly, when we recognise that brother and drives are different types, we mean that they belong to different word classes. We recognise seven MAJOR word classes:


Verb be, drive, grow, sing, think
Noun brother, car, David, house, London
Determiner a, an, my, some, the
Adjective big, foolish, happy, talented, tidy
Adverb happily, recently, soon, then, there
Preposition at, in, of, over, with
Conjunction and, because, but, if, or

You may find that other grammars recognise different word classes from the ones listed here. They may also define the boundaries between the classes in different ways. In some grammars, for instance, pronouns are treated as a separate word class, whereas we treat them as a subclass of nouns. A difference like this should not cause confusion. Instead, it highlights an important principle in grammar, known as GRADIENCE. This refers to the fact that the boundaries between the word classes are not absolutely fixed. Many word classes share characteristics with others, and there is considerable overlap between some of the classes. In other words, the boundaries are "fuzzy", so different grammars draw them in different places.
We will discuss each of the major word classes in turn. Then we will look briefly at some MINOR word classes. But first, let us consider how we distinguish between word classes in general.
1.1 Criteria for Word Classes
We began by grouping words more or less on the basis of our instincts about English. We somehow "feel" that brother and car belong to the same class, and that brother and drives belong to different classes. However, in order to conduct an informed study of grammar, we need a much more reliable and more systematic method than this for distinguishing between word classes.
We use a combination of three criteria for determining the word class of a word:

1. The meaning of the word
2. The form or `shape' of the word
3. The position or `environment' of the word in a sentence

1.1.1 Meaning
Using this criterion, we generalize about the kind of meanings that words convey. For example, we could group together the words brother and car, as well as David, house, and London, on the basis that they all refer to people, places, or things. In fact, this has traditionally been a popular approach to determining members of the class of nouns. It has also been applied to verbs, by saying that they denote some kind of "action", like cook, drive, eat, run, shout, walk.
This approach has certain merits, since it allows us to determine word classes by replacing words in a sentence with words of "similar" meaning. For instance, in the sentence My son cooks dinner every Sunday, we can replace the verb cooks with other "action" words:

My son cooks dinner every Sunday
My son prepares dinner every Sunday
My son eats dinner every Sunday
My son misses dinner every Sunday
On the basis of this replacement test, we can conclude that all of these words belong to the same class, that of "action" words, or verbs.
However, this approach also has some serious limitations. The definition of a noun as a word denoting a person, place, or thing, is wholly inadequate, since it excludes abstract nouns such as time, imagination, repetition, wisdom, and chance. Similarly, to say that verbs are "action" words excludes a verb like be, as in I want to be happy. What "action" does be refer to here? So although this criterion has a certain validity when applied to some words, we need other, more stringent criteria as well.

1.1.2 The form or `shape' of a word
Some words can be assigned to a word class on the basis of their form or `shape'. For example, many nouns have a characteristic -tion ending:

action, condition, contemplation, demonstration, organization, repetition
Similarly, many adjectives end in -able or -ible:

acceptable, credible, miserable, responsible, suitable, terrible
Many words also take what are called INFLECTIONS, that is, regular changes in their form under certain conditions. For example, nouns can take a plural inflection, usually by adding an -s at the end:

car -- cars
dinner -- dinners
book -- books
Verbs also take inflections:

walk -- walks -- walked -- walking

1.1.3 The position or `environment' of a word in a sentence
This criterion refers to where words typically occur in a sentence, and the kinds of words which typically occur near to them. We can illustrate the use of this criterion using a simple example. Compare the following:

[1] I cook dinner every Sunday
[2] The cook is on holiday

In [1], cook is a verb, but in [2], it is a noun. We can see that it is a verb in [1] because it takes the inflections which are typical of verbs:

I cook dinner every Sunday
I cooked dinner last Sunday
I am cooking dinner today
My son cooks dinner every Sunday
And we can see that cook is a noun in [2] because it takes the plural -s inflection

The cooks are on holiday
If we really need to, we can also apply a replacement test, based on our first criterion, replacing cook in each sentence with "similar" words:

Notice that we can replace verbs with verbs, and nouns with nouns, but we cannot replace verbs with nouns or nouns with verbs:

*I chef dinner every Sunday
*The eat is on holiday

It should be clear from this discussion that there is no one-to-one relation between words and their classes. Cook can be a verb or a noun -- it all depends on how the word is used. In fact, many words can belong to more than one word class. Here are some more examples:

She looks very pale (verb)
She's very proud of her looks (noun)
He drives a fast car (adjective)
He drives very fast on the motorway (adverb)
Turn on the light (noun)
I'm trying to light the fire (verb)
I usually have a light lunch (adjective)
You will see here that each italicised word can belong to more than one word class. However, they only belong to one word class at a time, depending on how they are used. So it is quite wrong to say, for example, "cook is a verb". Instead, we have to say something like "cook is a verb in the sentence I cook dinner every Sunday, but it is a noun in The cook is on holiday".
Of the three criteria for word classes that we have discussed here, the Internet Grammar will emphasise the second and third - the form of words, and how they are positioned or how they function in sentences.

1.2 Open and Closed Word Classes
Some word classes are OPEN, that is, new words can be added to the class as the need arises. The class of nouns, for instance, is potentially infinite, since it is continually being expanded as new scientific discoveries are made, new products are developed, and new ideas are explored. In the late twentieth century, for example, developments in computer technology have given rise to many new nouns:
Internet, website, URL, CD-ROM, email, newsgroup, bitmap, modem, multimedia
New verbs have also been introduced:
download, upload, reboot, right-click, double-click
The adjective and adverb classes can also be expanded by the addition of new words, though less prolifically.
On the other hand, we never invent new prepositions, determiners, or conjunctions. These classes include words like of, the, and but. They are called CLOSED word classes because they are made up of finite sets of words which are never expanded (though their members may change their spelling, for example, over long periods of time). The subclass of pronouns, within the open noun class, is also closed.
Words in an open class are known as open-class items. Words in a closed class are known as closed-class items.
In the pages which follow, we will look in detail at each of the seven major word classes.
2 Nouns

Nouns are commonly thought of as "naming" words, and specifically as the names of "people, places, or things". Nouns such as John, London, and computer certainly fit this description, but the class of nouns is much broader than this. Nouns also denote abstract and intangible concepts such as birth, happiness, evolution, technology, management, imagination, revenge, politics, hope, cookery, sport, literacy....
Because of this enormous diversity of reference, it is not very useful to study nouns solely in terms of their meaning. It is much more fruitful to consider them from the point of view of their formal characteristics.
2.1 Characteristics of Nouns
Many nouns can be recognised by their endings. Typical noun endings include:

-er/-or actor, painter, plumber, writer
-ism criticism, egotism, magnetism, vandalism
-ist artist, capitalist, journalist, scientist
-ment arrangement, development, establishment, government
-tion foundation, organisation, recognition, supposition

Most nouns have distinctive SINGULAR and PLURAL forms. The plural of regular nouns is formed by adding -s to the singular:

Singular Plural
car cars
dog dogs
house houses

However, there are many irregular nouns which do not form the plural in this way:

Singular Plural
man men
child children
sheep sheep

The distinction between singular and plural is known as NUMBER CONTRAST.
We can recognise many nouns because they often have the, a, or an in front of them:

the car
an artist
a surprise
the egg
a review
These words are called determiners, which is the next word class we will look at.
Nouns may take an -'s ("apostrophe s") or GENITIVE MARKER to indicate possession:

the boy's pen
a spider's web
my girlfriend's brother
John's house
If the noun already has an -s ending to mark the plural, then the genitive marker appears only as an apostrophe after the plural form:

the boys' pens
the spiders' webs
the Browns' house
The genitive marker should not be confused with the 's form of contracted verbs, as in John's a good boy (= John is a good boy).
Nouns often co-occur without a genitive marker between them:

rally car
table top
cheese grater
University entrance examination
We will look at these in more detail later, when we discuss noun phrases.

2.2 Common and Proper Nouns
Nouns which name specific people or places are known as PROPER NOUNS.

John
Mary
London
France
Many names consist of more than one word:

John Wesley
Queen Mary
South Africa
Atlantic Ocean
Buckingham Palace
Proper nouns may also refer to times or to dates in the calendar:

January, February, Monday, Tuesday, Christmas, Thanksgiving
All other nouns are COMMON NOUNS.
Since proper nouns usually refer to something or someone unique, they do not normally take plurals. However, they may do so, especially when number is being specifically referred to:

there are three Davids in my class
we met two Christmases ago
For the same reason, names of people and places are not normally preceded by determiners the or a/an, though they can be in certain circumstances:

it's nothing like the America I remember
my brother is an Einstein at maths

2.3 Count and Non-count Nouns
Common nouns are either count or non-count. COUNT nouns can be "counted", as follows:

one pen, two pens, three pens, four pens...
NON-COUNT nouns, on the other hand, cannot be counted in this way:

one software, *two softwares, *three softwares, *four softwares...
From the point of view of grammar, this means that count nouns have singular as well as plural forms, whereas non-count nouns have only a singular form.
It also means that non-count nouns do not take a/an before them:

Count Non-count
a pen *a software

In general, non-count nouns are considered to refer to indivisible wholes. For this reason, they are sometimes called MASS nouns.
Some common nouns may be either count or non-count, depending on the kind of reference they have. For example, in I made a cake, cake is a count noun, and the a before it indicates singular number. However, in I like cake, the reference is less specific. It refers to "cake in general", and so cake is non-count in this sentence.
2.4 Pronouns
Pronouns are a major subclass of nouns. We call them a subclass of nouns because they can sometimes replace a noun in a sentence:

Noun Pronoun
John got a new job ~He got a new job
Children should watch less television ~They should watch less television

In these examples the pronouns have the same reference as the nouns which they replace. In each case, they refer to people, and so we call them PERSONAL PRONOUNS. However, we also include in this group the pronoun it, although this pronoun does not usually refer to a person. There are three personal pronouns, and each has a singular and a plural form:

Person Singular Plural
1st I we
2nd you you
3rd he/she/it they

These pronouns also have another set of forms, which we show here:

Person Singular Plural
1st me us
2nd you you
3rd him/her/it them

The first set of forms (I, you, he...) exemplifies the SUBJECTIVE CASE, and the second set (me, you, him...) exemplifies the OBJECTIVE CASE. The distinction between the two cases relates to how they can be used in sentences. For instance, in our first example above, we say that he can replace John

John got a new job ~He got a new job

But he cannot replace John in I gave John a new job. Here, we have to use the objective form him: I gave him a new job.
2.5 Other Types of Pronoun
As well as personal pronouns, there are many other types, which we summarise here.

Pronoun Type Members of the Subclass Example
Possessive mine, yours, his, hers, ours, theirs The white car is mine
Reflexive myself, yourself, himself, herself, itself, oneself, ourselves, yourselves, themselves He injured himself playing football
Reciprocal each other, one another They really hate each other
Relative that, which, who, whose, whom, where, when The book that you gave me was really boring
Demonstrative this, that, these, those This is a new car
Interrogative who, what, why, where, when, whatever What did he say to you?
Indefinite anything, anybody, anyone, something, somebody, someone, nothing, nobody, none, no one There's something in my shoe

Case and number distinctions do not apply to all pronoun types. In fact, they apply only to personal pronouns, possessive pronouns, and reflexive pronouns. It is only in these types, too, that gender differences are shown (personal he/she, possessive his/hers, reflexive himself/herself). All other types are unvarying in their form.
Many of the pronouns listed above also belong to another word class - the class of determiners. They are pronouns when they occur independently, that is, without a noun following them, as in This is a new car. But when a noun follows them - This car is new - they are determiners. We will look at determiners in the next section.
A major difference between pronouns and nouns generally is that pronouns do not take the or a/an before them. Further, pronouns do not take adjectives before them, except in very restricted constructions involving some indefinite pronouns (a little something, a certain someone).
While the class of nouns as a whole is an open class, the subclass of pronouns is closed.
2.6 Numerals
Numerals include all numbers, whether as words or as digits. They may be divided into two major types. CARDINAL numerals include words like:

nought, zero, one, two, 3, fifty-six, 100, a thousand
ORDINAL numerals include

first, 2nd, third, fourth, 500th
We classify numerals as a subclass of nouns because in certain circumstances they can take plurals:

five twos are ten
he's in his eighties
They may also take the:

the fourth of July
a product of the 1960s
And some plural numerals can take an adjective before them, just like other nouns:

the house was built in the late 1960s
he's in his early twenties
the temperature is in the high nineties
In each of our examples, the numerals occur independently, that is, without a noun following them. In these positions, we can classify them as a type of noun because they behave in much the same way as nouns do. Notice, for example, that we can replace the numerals in our examples with common nouns:

he is in his eighties ~he is in his bedroom
the fourth of July ~the beginning of July
a product of the 1960s ~a product of the revolution

Numerals do not always occur independently. They often occur before a noun, as in

one day
three pages
the fourth day of July
In this position, we classify them as determiners, which we will examine in the next section.
Finally, see if you can answer this question:
Is the subclass of numerals open or closed?
2.7 The Gender of Nouns
The gender of nouns plays an important role in the grammar of some languages. In French, for instance, a masculine noun can only take the masculine form of an adjective. If the noun is feminine, then it will take a different form of the same adjective - its feminine form.
In English, however, nouns are not in themselves masculine or feminine. They do not have grammatical gender, though they may refer to male or female people or animals:

the waiter is very prompt ~the waitress is very prompt
the lion roars at night ~the lioness roars at night

These distinctions in spelling reflect differences in sex, but they have no grammatical implications. For instance, we use the same form of an adjective whether we are referring to a waiter or to a waitress:

an efficient waiter ~an efficient waitress

Similarly, the natural distinctions reflected in such pairs as brother/sister, nephew/niece, and king/queen have no consequence for grammar. While they refer to specific sexes, these words are not masculine or feminine in themselves.
However, gender is significant in the choice of a personal pronoun to replace a noun:

John is late ~He is late
Mary is late ~She is late

Here the choice of pronoun is determined by the sex of the person being referred to. However, this distinction is lost in the plural:

John and Mary are late ~They are late
John and David are late ~They are late
Mary and Jane are late ~They are late

Gender differences are also manifested in possessive pronouns (his/hers) and in reflexive pronouns (himself/herself).
When the notion of sex does not apply -- when we refer to inanimate objects, for instance -- we use the pronoun it:

the letter arrived late ~it arrived late

3 Determiners

Nouns are often preceded by the words the, a, or an. These words are called DETERMINERS. They indicate the kind of reference which the noun has. The determiner the is known as the DEFINITE ARTICLE. It is used before both singular and plural nouns:


Singular Plural
the taxi the taxis
the paper the papers
the apple the apples

The determiner a (or an, when the following noun begins with a vowel) is the INDEFINITE ARTICLE. It is used when the noun is singular:

a taxi
a paper
an apple
The articles the and a/an are the most common determiners, but there are many others:

any taxi
that question
those apples
this paper
some apple
whatever taxi
whichever taxi
Many determiners express quantity:

all examples
both parents
many people
each person
every night
several computers
few excuses
enough water
no escape
Perhaps the most common way to express quantity is to use a numeral. We look at numerals as determiners in the next section.
3.1 Numerals and Determiners
Numerals are determiners when they appear before a noun. In this position, cardinal numerals express quantity:

one book
two books
twenty books
In the same position, ordinal numerals express sequence:

first impressions
second chance
third prize
The subclass of ordinals includes a set of words which are not directly related to numbers (as first is related to one, second is related to two, etc). These are called general ordinals, and they include last, latter, next, previous, and subsequent. These words also function as determiners:

next week
last orders
previous engagement
subsequent developments
When they do not come before a noun, as we've already seen, numerals are a subclass of nouns. And like nouns, they can take determiners:

the two of us
the first of many
They can even have numerals as determiners before them:

five twos are ten
In this example, twos is a plural noun and it has the determiner five before it.
3.2 Pronouns and Determiners
There is considerable overlap between the determiner class and the subclass of pronouns. Many words can be both:


Pronoun Determiner
This is a very boring book This book is very boring
That's an excellent film That film is excellent

As this table shows, determiners always come before a noun, but pronouns are more independent than this. They function in much the same way as nouns, and they can be replaced by nouns in the sentences above:


This is a very boring book ~Ivanhoe is a very boring book
That's an excellent film ~Witness is an excellent film

On the other hand, when these words are determiners, they cannot be replaced by nouns:


This book is very boring ~*Ivanhoe book is very boring
That film is excellent ~*Witness film is excellent

The personal pronouns (I, you, he, etc) cannot be determiners. This is also true of the possessive pronouns (mine, yours, his/hers, ours, and theirs). However, these pronouns do have corresponding forms which are determiners:


Possessive Pronoun Determiner
The white car is mine My car is white
Yours is the blue coat Your coat is blue
The car in the garage is his/hers His/her car is in the garage
David's house is big, but ours is bigger Our house is bigger than David's
Theirs is the house on the left Their house is on the left

The definite and the indefinite articles can never be pronouns. They are always determiners.
3.3 The Ordering of Determiners
Determiners occur before nouns, and they indicate the kind of reference which the nouns have. Depending on their relative position before a noun, we distinguish three classes of determiners.


Predeterminer Central Determiner Postdeterminer Noun
I met all my many friends

A sentence like this is somewhat unusual, because it is rare for all three determiner slots to be filled in the same sentence. Generally, only one or two slots are filled.
3.4 Predeterminers
Predeterminers specify quantity in the noun which follows them, and they are of three major types:
1. "Multiplying" expressions, including expressions ending in times:

twice my salary
double my salary
ten times my salary
2. Fractions

half my salary
one-third my salary
3. The words all and both:

all my salary
both my salaries
Predeterminers do not normally co-occur:

*all half my salary

3.5 Central Determiners
The definite article the and the indefinite article a/an are the most common central determiners:

all the book
half a chapter
As many of our previous examples show, the word my can also occupy the central determiner slot. This is equally true of the other possessives:

all your money
all his/her money
all our money
all their money
The demonstratives, too, are central determiners:

all these problems
twice that size
four times this amount

3.6 Postdeterminers
Cardinal and ordinal numerals occupy the postdeterminer slot:

the two children
his fourth birthday
This applies also to general ordinals:

my next project
our last meeting
your previous remark
her subsequent letter
Other quantifying expressions are also postdeterminers:

my many friends
our several achievements
the few friends that I have
Unlike predeterminers, postdeterminers can co-occur:

my next two projects
several other people

4 Verbs

Verbs have traditionally been defined as "action" words or "doing" words. The verb in the following sentence is rides:
Paul rides a bicycle
Here, the verb rides certainly denotes an action which Paul performs - the action of riding a bicycle. However, there are many verbs which do not denote an action at all. For example, in Paul seems unhappy, we cannot say that the verb seems denotes an action. We would hardly say that Paul is performing any action when he seems unhappy. So the notion of verbs as "action" words is somewhat limited.
We can achieve a more robust definition of verbs by looking first at their formal features.
4.1 The Base Form
Here are some examples of verbs in sentences:
[1] She travels to work by train
[2] David sings in the choir
[3] We walked five miles to a garage
[4] I cooked a meal for the family
Notice that in [1] and [2], the verbs have an -s ending, while in [3] and [4], they have an -ed ending. These endings are known as INFLECTIONS, and they are added to the BASE FORM of the verb. In [1], for instance, the -s inflection is added to the base form travel.
Certain endings are characteristic of the base forms of verbs:


Ending Base Form
-ate concentrate, demonstrate, illustrate
-ify clarify, dignify, magnify
-ise/-ize baptize, conceptualize, realise

4.2 Past and Present Forms
When we refer to a verb in general terms, we usually cite its base form, as in "the verb travel", "the verb sing". We then add inflections to the base form as required.


Base Form + Inflection
[1] She travel + s to work by train
[2] David sing + s in the choir
[3] We walk + ed five miles to a garage
[4] I cook + ed a meal for the whole family

These inflections indicate TENSE. The -s inflection indicates the PRESENT TENSE, and the -ed inflection indicates the PAST TENSE.
Verb endings also indicate PERSON. Recall that when we looked at nouns and pronouns, we saw that there are three persons, each with a singular and a plural form. These are shown in the table below.


Person Singular Plural
1st Person I we
2nd person you you
3rd Person he/she/John/the dog they/the dogs

In sentence [1], She travels to work by train, we have a third person singular pronoun she, and the present tense ending -s. However, if we replace she with a plural pronoun, then the verb will change:
[1] She travels to work by train
[1a] They travel to work by train
The verb travel in [1a] is still in the present tense, but it has changed because the pronoun in front of it has changed. This correspondence between the pronoun (or noun) and the verb is called AGREEMENT or CONCORD. Agreement applies only to verbs in the present tense. In the past tense, there is no distinction between verb forms: she travelled/they travelled.
4.3 The Infinitive Form
The INFINITIVE form of a verb is the form which follows to:


to ask
to believe
to cry
to go to protect
to sing
to talk
to wish

This form is indistinguishable from the base form. Indeed, many people cite this form when they identify a verb, as in "This is the verb to be", although to is not part of the verb.
Infinitives with to are referred to specifically as TO-INFINITIVES, in order to distinguish them from BARE INFINITIVES, in which to is absent:


To-infinitive Bare infinitive

4.4 More Verb Forms: -ing and -ed
So far we have looked at three verb forms: the present form, the past form, and the infinitive/base form. Verbs have two further forms which we will look at now.
[1] The old lady is writing a play
[2] The film was produced in Hollywood
The verb form writing in [1] is known as the -ing form, or the -ING PARTICIPLE form. In [2], the verb form produced is called the -ed form, or -ED PARTICIPLE form.
Many so-called -ed participle forms do not end in -ed at all:
The film was written by John Brown
The film was bought by a British company
The film was made in Hollywood
All of these forms are called -ed participle forms, despite their various endings. The term "-ed participle form" is simply a cover term for all of these forms.
The -ed participle form should not be confused with the -ed inflection which is used to indicate the past tense of many verbs.
We have now looked at all five verb forms. By way of summary, let us bring them together and see how they look for different verbs. For convenience, we will illustrate only the third person singular forms (the forms which agree with he/she/it) of each verb. Notice that some verbs have irregular past forms and -ed forms.


Base/Infinitive Form Present Tense Form Past Tense Form -ing Form -ed Form
cook he cooks he cooked he is cooking he has cooked
walk he walks he walked he is walking he has walked
take he takes he took he is taking he has taken
bring he brings he brought he is bringing he has brought
be he is he was he is being he has been
4.5 Finite and Nonfinite Verbs
Verbs which have the past or the present form are called FINITE verbs. Verbs in any other form (infinitive, -ing, or -ed) are called NONFINITE verbs. This means that verbs with tense are finite, and verbs without tense are nonfinite. The distinction between finite and nonfinite verbs is a very important one in grammar, since it affects how verbs behave in sentences. Here are some examples of each type:


Tense Finite or Nonfinite?
David plays the piano Present Finite
My sister spoke French on holiday Past Finite
It took courage to continue after the accident NONE -- the verb has the infinitive form Nonfinite
Leaving home can be very traumatic NONE -- the verb has the -ing form Nonfinite
Leave immediately when you are asked to do so NONE -- the verb has the -ed form Nonfinite
4.6 Auxiliary Verbs
In the examples of -ing and -ed forms which we looked at, you may have noticed that in each case two verbs appeared:

[1] The old lady is writing a play
[2] The film was produced in Hollywood
Writing and produced each has another verb before it. These other verbs (is and was) are known as AUXILIARY VERBS, while writing and produced are known as MAIN VERBS or LEXICAL VERBS. In fact, all the verbs we have looked at on the previous pages have been main verbs.
Auxiliary verbs are sometimes called HELPING VERBS. This is because they may be said to "help" the main verb which comes after them. For example, in The old lady is writing a play, the auxiliary is helps the main verb writing by specifying that the action it denotes is still in progress.
4.7 Auxiliary Verb Types
In this section we will give a brief account of of each type of auxiliary verb in English. There are five types in total:


Passive be This is used to form passive constructions, eg.
The film was produced in Hollywood
It has a corresponding present form:
The film is produced in Hollywood

We will return to passives later, when we look at voice.
Progressive be As the name suggests, the progressive expresses action in progress:
The old lady is writing a play
It also has a past form:
The old lady was writing a play
Perfective have The perfective auxiliary expresses an action accomplished in the past but retaining current relevance:
She has broken her leg
(Compare: She broke her leg)

Together with the progressive auxiliary, the perfective auxiliary encodes aspect, which we will look at later.
Modal can/could
may/might
shall/should
will/would
must Modals express permission, ability, obligation, or prediction:
You can have a sweet if you like
He may arrive early
Paul will be a footballer some day
I really should leave now
Dummy Do This subclass contains only the verb do. It is used to form questions:
Do you like cheese?
to form negative statements:
I do not like cheese
and in giving orders:
Do not eat the cheese
Finally, dummy do can be used for emphasis:
I do like cheese

An important difference between auxiliary verbs and main verbs is that auxiliaries never occur alone in a sentence. For instance, we cannot remove the main verb from a sentence, leaving only the auxiliary:


I would like a new job ~*I would a new job
You should buy a new car ~*You should a new car
She must be crazy ~*She must crazy

Auxiliaries always occur with a main verb. On the other hand, main verbs can occur without an auxiliary.

I like my new job
I bought a new car
She sings like a bird
In some sentences, it may appear that an auxiliary does occur alone. This is especially true in responses to questions:

Q. Can you sing?
A. Yes, I can
Here the auxiliary can does not really occur without a main verb, since the main verb -- sing -- is in the question. The response is understood to mean:

Yes, I can sing
This is known as ellipsis -- the main verb has been ellipted from the response.
Auxiliaries often appear in a shortened or contracted form, especially in informal contexts. For instance, auxiliary have is often shortened to 've:

I have won the lottery ~I've won the lottery
These shortened forms are called enclitic forms. Sometimes different auxiliaries have the same enclitic forms, so you should distinguish carefully between them:

I'd like a new job ( = modal auxiliary would)
We'd already spent the money by then ( = perfective auxiliary had)
He's been in there for ages ( = perfective auxiliary has)
She's eating her lunch ( = progressive auxiliary is)
The following exercise concentrates on three of the most important auxiliaries -- be, have, and do.
4.8 The NICE Properties of Auxiliaries
The so-called NICE properties of auxiliaries serve to distinguish them from main verbs. NICE is an acronym for:


Negation Auxiliaries take not or n't to form the negative, eg. cannot, don't, wouldn't
Inversion Auxiliaries invert with what precedes them when we form questions:
[I will] see you soon ~[Will I] see you soon?
Code Auxiliaries may occur "stranded" where a main verb has been omitted:
John never sings, but Mary does
Emphasis Auxiliaries can be used for emphasis:
I do like cheese

Main verbs do not exhibit these properties. For instance, when we form a question using a main verb, we cannot invert:

[John sings] in the choir ~*[Sings John] in the choir?
Instead, we have to use the auxiliary verb do:

[John sings] in the choir ~[Does John sing] in the choir?

4.9 Semi-auxiliaries
Among the auxiliary verbs, we distinguish a large number of multi-word verbs, which are called SEMI-AUXILIARIES. These are two-or three-word combinations, and they include the following:


get to
happen to
have to
mean to seem to
tend to
turn out to
used to be about to
be going to
be likely to
be supposed to

Like other auxiliaries, the semi-auxiliaries occur before main verbs:

The film is about to start
I'm going to interview the Lord Mayor
I have to leave early today
You are supposed to sign both forms
I used to live in that house
Some of these combinations may, of course, occur in other contexts in which they are not semi-auxiliaries. For example:

I'm going to London
Here, the combination is not a semi-auxiliary, since it does not occur with a main verb. In this sentence, going is a main verb. Notice that it could be replaced by another main verb such as travel (I'm travelling to London). The word 'm is the contracted form of am, the progressive auxiliary, and to, as we'll see later, is a preposition.
4.10 Tense and Aspect
TENSE refers to the absolute location of an event or action in time, either the present or the past. It is marked by an inflection of the verb:
David walks to school (present tense)
David walked to school (past tense)
Reference to other times -- the future, for instance -- can be made in a number of ways, by using the modal auxiliary will, or the semi-auxiliary be going to:
David will walk to school tomorrow
David is going to walk to school tomorrow.
Since the expression of future time does not involve any inflecton of the verb, we do not refer to a "future tense". Strictly speaking, there are only two tenses in English: present and past.
ASPECT refers to how an event or action is to be viewed with respect to time, rather than to its actual location in time. We can illustrate this using the following examples:
[1] David fell in love on his eighteenth birthday
[2] David has fallen in love
[3] David is falling in love
In [1], the verb fell tells us that David fell in love in the past, and specifically on his eighteenth birthday. This is a simple past tense verb.
In [2] also, the action took place in the past, but it is implied that it took place quite recently. Furthermore, it is implied that is still relevant at the time of speaking -- David has fallen in love, and that's why he's behaving strangely. It is worth noting that we cannot say *David has fallen in love on his eighteenth birthday. The auxiliary has here encodes what is known as PERFECTIVE ASPECT, and the auxiliary itself is known as the PERFECTIVE AUXILIARY.
In [3], the action of falling in love is still in progress -- David is falling in love at the time of speaking. For this reason, we call it PROGRESSIVE ASPECT, and the auxiliary is called the PROGRESSIVE AUXILIARY.
Aspect always includes tense. In [2] and [3] above, the aspectual auxiliaries are in the present tense, but they could also be in the past tense:
David had fallen in love -- Perfective Aspect, Past Tense
David was falling in love -- Progressive Aspect, Past Tense
The perfective auxiliary is always followed by a main verb in the -ed form, while the progressive auxiliary is followed by a main verb in the -ing form. We exemplify these points in the table below:


Perfective Aspect Progressive Aspect
Present Tense has fallen is falling
Past Tense had fallen was falling

While aspect always includes tense, tense can occur without aspect (David falls in love, David fell in love).
4.11 Voice
There are two voices in English, the active voice and the passive voice:


Active Voice Passive Voice
[1] Paul congratulated David [2] David was congratulated by Paul

Passive constructions are formed using the PASSIVE AUXILIARY be, and the main verb has an -ed inflection. In active constructions, there is no passive auxiliary, though other auxiliaries may occur:
Paul is congratulating David
Paul will congratulate David
Paul has congratulated David
All of these examples are active constructions, since they contain no passive auxiliary. Notice that in the first example (Paul is congratulating David), the auxiliary is the progressive auxiliary, not the passive auxiliary. We know this because the main verb congratulate has an -ing inflection, not an -ed inflection.
In the passive construction in [2], we refer to Paul as the AGENT. This is the one who performs the action of congratulating David. Sometimes no agent is specified:
David was congratulated
We refer to this as an AGENTLESS PASSIVE
5 Adjectives

Adjectives can be identified using a number of formal criteria. However, we may begin by saying that they typically describe an attribute of a noun:

cold weather
large windows
violent storms

Some adjectives can be identified by their endings. Typical adjective endings include:


-able/-ible achievable, capable, illegible, remarkable
-al biographical, functional, internal, logical
-ful beautiful, careful, grateful, harmful
-ic cubic, manic, rustic, terrific
-ive attractive, dismissive, inventive, persuasive
-less breathless, careless, groundless, restless
-ous courageous, dangerous, disastrous, fabulous

However, a large number of very common adjectives cannot be identified in this way. They do not have typical adjectival form:


bad
bright
clever
cold
common
complete
dark
deep
difficult distant
elementary
good
great
honest
hot
main
morose
old quiet
real
red
silent
simple
strange
wicked
wide
young

As this list shows, adjectives are formally very diverse. However, they have a number of characteristics which we can use to identify them.
5.1 Characteristics of Adjectives
Adjectives can take a modifying word, such as very, extremely, or less, before them:

very cold weather
extremely large windows
less violent storms

Here, the modifying word locates the adjective on a scale of comparison, at a position higher or lower than the one indicated by the adjective alone.
This characteristic is known as GRADABILITY. Most adjectives are gradable, though if the adjective already denotes the highest position on a scale, then it is non-gradable:


my main reason for coming ~*my very main reason for coming
the principal role in the play ~*the very principal role in the play


As well as taking modifying words like very and extremely,adjectives also take different forms to indicate their position on a scale of comparison:

big bigger biggest

The lowest point on the scale is known as the ABSOLUTE form, the middle point is known as the COMPARATIVE form, and the highest point is known as the SUPERLATIVE form. Here are some more examples:


Absolute Comparative Superlative
dark darker darkest
new newer newest
old older oldest
young younger youngest

In most cases, the comparative is formed by adding -er , and the superlative is formed by adding -est, to the absolute form. However, a number of very common adjectives are irregular in this respect:


Absolute Comparative Superlative
good better best
bad worse worst
far farther farthest

Some adjectives form the comparative and superlative using more and most respectively:


Absolute Comparative Superlative
important more important most important
miserable more miserable most miserable
recent more recent most recent
5.2 Attributive and Predicative Adjectives
Most adjectives can occur both before and after a noun:



the blue sea ~ the sea is blue
the old man ~ the man is old
happy children ~ the children are happy

Adjectives in the first position - before the noun - are called ATTRIBUTIVE adjectives. Those in the second position - after the noun - are called PREDICATIVE adjectives. Notice that predicative adjectives do not occur immediately after the noun. Instead, they follow a verb.
Sometimes an adjective does occur immediately after a noun, especially in certain institutionalised expressions:
the Governor General
the Princess Royal
times past
We refer to these as POSTPOSITIVE adjectives. Postposition is obligatory when the adjective modifies a pronoun:
something useful
everyone present
those responsible
Postpositive adjectives are commonly found together with superlative, attributive adjectives:
the shortest route possible
the worst conditions imaginable
the best hotel available
Most adjectives can freely occur in both the attributive and the predicative positions. However, a small number of adjectives are restricted to one position only. For example, the adjective main (the main reason) can only occur in the attributive position (predicative: *the reason is main). Conversely, the adjective afraid (the child was afraid) can only occur predicatively (attributive: *an afraid child).
We have now looked at the main criteria for the adjective class - gradability, comparative and superlative forms, and the ability to occur attributively and predicatively. Most adjectives fulfil all these criteria, and are known as CENTRAL adjectives. Those which do not fulfil all the criteria are known as PERIPHERAL adjectives.
We will now examine the adjective class in more detail.
5.3 Inherent and Non-inherent Adjectives
Most attributive adjectives denote some attribute of the noun which they modify. For instance, the phrase a red car may be said to denote a car which is red. In fact most adjective-noun sequences such as this can be loosely reformulated in a similar way:


an old man ~a man who is old
difficult questions ~questions which are difficult
round glasses ~glasses which are round

This applies equally to postpositive adjectives:
something understood ~something which is understood
the people responsible ~the people who are responsible
In each case the adjective denotes an attribute or quality of the noun, as the reformulations show. Adjectives of this type are known as INHERENT adjectives. The attribute they denote is, as it were, inherent in the noun which they modify.
However, not all adjectives are related to the noun in the same way. For example, the adjective small in a small businessman does not describe an attribute of the businessman. It cannot be reformulated as a businessman who is small. Instead, it refers to a businessman whose business is small. We refer to adjectives of this type as NON-INHERENT adjectives. They refer less directly to an attribute of the noun than inherent adjectives do. Here are some more examples, showing the contrast betwen inherent and non-inherent:


Inherent Non-inherent
distant hills distant relatives
a complete chapter a complete idiot
a heavy burden a heavy smoker
a social survey a social animal
an old man an old friend
5.4 Stative and Dynamic Adjectives
As their name suggests, STATIVE adjectives denote a state or condition, which may generally be considered permanent, such as big, red, small. Stative adjectives cannot normally be used in imperative constructions:

*Be big/red/small
Further, they cannot normally be used in progressive constructions:

*He is being big/red/small
In contrast, DYNAMIC adjectives denote attributes which are, to some extent at least, under the control of the one who possesses them. For instance, brave denotes an attribute which may not always be in evidence (unlike red, for example), but which may be called upon as it is required. For this reason, it is appropriate to use it in an imperative:

Be brave!
Dynamic adjectives include:


calm
careful
cruel
disruptive
foolish
friendly
good
impatient mannerly
patient
rude
shy
suspicious
tidy
vacuous
vain

All dynamic adjectives can be used in imperatives (Be careful!, Don't be cruel!), and they can also be used predicatively in progressive constructions:

Your son is being disruptive in class
My parents are being foolish again
We're being very patient with you
The majority of adjectives are stative. The stative/dynamic contrast, as it relates to adjectives, is largely a semantic one, though as we have seen it also has syntactic implications.
5.5 Nominal Adjectives
Certain adjectives are used to denote a class by describing one of the attributes of the class. For example, the poor denotes a class of people who share a similar financial status. Other nominal adjectives are:
the old
the sick
the wealthy
the blind
the innocent
A major subclass of nominal adjectives refers to nationalities:

the French
the British
the Japanese
However, not all nationalities have corresponding nominal adjectives. Many of them are denoted by plural, proper nouns:

the Germans
the Russians
the Americans
the Poles

Nominal adjectives do not refer exclusively to classes of people. Indeed some of them do not denote classes at all:

the opposite
the contrary
the good
Comparative and superlative forms can also be nominal adjectives:

the best is yet to come
the elder of the two
the greatest of these
the most important among them
We refer to all of these types as nominal adjectives because they share some of the characteristics of nouns (hence `nominal') and some of the characteristics of adjectives. They have the following nominal characteristics:
• they are preceded by a determiner (usually the definite article the)
• they can be modified by adjectives (the gallant French, the unfortunate poor)
They have the following adjectival features:

• they are gradable (the very old, the extremely wealthy)
• many can take comparative and superlative forms (the poorer, the poorest)
5.6 Adjectives and Nouns
We have seen that attributive adjectives occur before a noun which they modify, for example, red in red car. We need to distinguish these clearly from nouns which occur in the same position, and fulfil the same syntactic function. Consider the following:

rally car
saloon car
family car
Here, the first word modifies the second, that is, it tells us something further about the car. For example, a rally car is a car which is driven in rallies. These modifiers occur in the same position as red in the example above, but they are not adjectives. We can show this by applying our criteria for the adjective class.
Firstly, they do not take very:

*a very rally car
*a very saloon car
*a very family car
Secondly, they do not have comparative or superlative forms:

*rallier *ralliest / *more rally / *most rally
*salooner *saloonest / *more saloon / *most saloon
*familier *familiest / *more family / *most family

And finally, they cannot occur in predicative position:

*the car is rally
*the car is saloon
*the car is family
So although these words occupy the typical adjective position, they are not adjectives. They are nouns.
However, certain adjectives are derived from nouns, and are known as DENOMINAL adjectives. Examples include:

a mathematical puzzle [`a puzzle based on mathematics']
a biological experiment [`an experiment in biology']
a wooden boat [`a boat made of wood']

Denominals include adjectives which refer to nationality:

a Russian lady [`a lady who comes from Russia']
German goods [`goods produced in Germany']

Denominal adjectives of this type should be carefully distinguished from nominal adjectives denoting nationalities. Compare:

Nominal Adjective: The French are noted for their wines
Denominal Adjective: The French people are noted for their wines
5.7 Participial Adjectives
We saw in an earlier section that many adjectives can be identified by their endings. Another major subclass of adjectives can also be formally distinguished by endings, this time by -ed or -ing endings:


-ed form computerized, determined, excited, misunderstood, renowned, self-centred, talented, unknown
-ing form annoying, exasperating, frightening, gratifying, misleading, thrilling, time-consuming, worrying

Remember that some -ed forms, such as misunderstood and unknown, do not end in -ed at all. This is simply a cover term for this form. Adjectives with -ed or -ing endings are known as PARTICIPIAL ADJECTIVES, because they have the same endings as verb participles (he was training for the Olympics, he had trained for the Olympics). In some cases there is a verb which corresponds to these adjectives (to annoy, to computerize, to excite, etc), while in others there is no corresponding verb (*to renown, *to self-centre, *to talent). Like other adjectives, participial adjectives can usually be modified by very, extremely, or less (very determined, extremely self-centred, less frightening, etc). They can also take more and most to form comparatives and superlatives (annoying, more annoying, most annoying). Finally, most participial adjectives can be used both attributively and predicatively:


Attributive Predicative
That's an irritating noise That noise is irritating
This is an exciting film This film is exciting
He's a talented footballer That footballer is talented

Many participial adjectives, which have no corresponding verb, are formed by combining a noun with a participle:

alcohol-based chemicals
battle-hardened soldiers
drug-induced coma
energy-saving devices
fact-finding mission
purpose-built accommodation
These, too, can be used predicatively (the chemicals are alcohol-based, the soldiers were battle-hardened, etc).
When participial adjectives are used predicatively, it may sometimes be difficult to distinguish between adjectival and verbal uses:

[1] the workers are striking
In the absence of any further context, the grammatical status of striking is indeterminate here. The following expansions illustrate possible adjectival [1a] and verbal [1b] readings of [1]:

[1a] the workers are very striking in their new uniforms (=`impressive', `conspicuous')
[1b] the workers are striking outside the factory gates (=`on strike')
Consider the following pair:

[2] the noise is annoying
[3] the noise is annoying the neighbours
In [2], we can modify annoying using very:

[2a] the noise is (very) annoying
But we cannot modify it in the same way in [3]:

[3a] *the noise is (very) annoying the neighbours
The acceptability of [2a] indicates that annoying is an adjective in this construction. In [3], the verbal nature of annoying is indicated by the fact that we cannot add very , as in [3a]. It is further indicated by the presence of the neighbours (the direct object) after annoying. Notice also that we can turn [3] into a passive sentence (the neighbours were annoyed by the noise). In this case, annoying is the main verb of the sentence, and it is preceded by the progressive auxiliary verb is. In [2], there is only one verb, the main verb is.
We can distinguish between the following pairs using the same criteria:


Adjectival Verbal
This film is terrifying This film is terrifying the children
Your comments are alarming Your comments are alarming the people
The defendant's answers were misleading The defendant's answers were misleading the jury

We can also identify -ing forms as verbal if it is possible to change the -ing form into a non-progressive verb:


Progressive Non-progressive
The children are dancing The children dance
My eyes are stinging My eyes sting
The wood is drying The wood dries

Compare these changes from progressive to non-progressive with the following:


the work is rewarding ~*the work rewards
the job was exacting ~*the job exacted
your paper was interesting ~*your paper interested

In these instances, the inability to produce fully acceptable non-progressive sentences indicates adjectival use.
Similar indeterminacy occurs with -ed forms. Again, we can generally use very to determine whether the -ed word is adjectival or verbal:


The bomb was detonated ~*The bomb was very detonated
This document is hand-written ~*This document is very hand-written
My house was built in only twelve weeks ~*My house was very built in only twelve weeks
Ten people were killed ~*Ten people were very killed

The inability to supply very in these cases indicates a verbal rather than an adjectival construction. However, this test is less reliable with -ed forms than it is with -ing forms, since very can sometimes be supplied in both the adjectival and the verbal constructions:


Adjectival Verbal
I was embarrassed
I was very embarrassed I was embarrassed by your behaviour
I was very embarrassed by your behaviour
She was surprised
She was very surprised She was surprised by my reaction
She was very surprised by my reaction

The presence of a by-agent phrase (by your behaviour, by my reaction) indicates that the -ed form is verbal. Conversely, the presence of a complement, such as a that-clause, indicates that it is adjectival. Compare the following two constructions:


Adjectival: The jury was convinced that the defendant was innocent
Verbal: The jury was convinced by the lawyer's argument

Here are some further examples of adjectival constructions (with complements) and verbal constructions (with by-agent phrases):


Adjectival Verbal
I was delighted to meet you again I was delighted by his compliments
John is terrified of losing his job John is terrified by his boss
I was frightened that I'd be late I was frightened by your expression
I was disappointed to hear your decision I was disappointed by your decision

If the -ed form is verbal, we can change the passive construction in which it occurs into an active one:


Passive: I was delighted by his compliments
Active: His compliments delighted me

For more on active and passive constructions, see...

As we have seen, discriminating between adjectival and verbal constructions is sometimes facilitated by the presence of additional context, such as by-agent phrases or adjective complements. However, when none of these indicators is present, grammatical indeterminacy remains. Consider the following examples from conversational English:
And you know if you don't know the simple command how to get out of something you're sunk [S1A-005-172]
But that's convenient because it's edged with wood isn't it [S1A-007-97]
With -ed and -ing participial forms, there is no grammatical indeterminacy if there is no corresponding verb. For example, in the job was time-consuming, and the allegations were unfounded, the participial forms are adjectives.
Similarly, the problem does not arise if the main verb is not be. For example, the participial forms in this book seems boring, and he remained offended are all adjectives. Compare the following:

John was depressed
John felt depressed
5.8 The Ordering of Adjectives
When two or more adjectives come before a noun, their relative order is fixed to a certain degree. This means, for instance, that while complex mathematical studies is grammatically acceptable, mathematical complex studies is less so. Similarly:


a huge red bomber ~*a red huge bomber
a long narrow road ~*a narrow long road
the lovely little black Japanese box ~*the Japanese black little lovely box

Here we will discuss some of the most common sequences which occur, though these should not be seen as ordering rules. Counter examples can often be found quite easily.
Central adjectives, as we saw earlier, are adjectives which fulfil all the criteria for the adjective class. In this sense, they are more "adjectival" than, say, denominal adjectives, which also have some of the properties of nouns.
This distinction has some significance in the ordering of adjectives. In general, the more adjectival a word is, the farther from the noun it will be. Conversely, the less adjectival it is (the more nominal), the nearer to the noun it will be. The relative order of these adjective types, then, is:
Sequence (1): CENTRAL -- DENOMINAL -- NOUN
This is the ordering found in complex mathematical studies, for instance, and also in the following examples:

expensive Russian dolls
heavy woollen clothes
huge polar bears
Colour adjectives are also central adjectives, but if they co-occur with another central adjective, they come after it:
Sequence (2): CENTRAL -- COLOUR -- NOUN

expensive green dolls
heavy black clothes
huge white bears
and before denominal adjectives:
Sequence (3): COLOUR -- DENOMINAL -- NOUN

green Russian dolls
black woollen clothes
white polar bears
Participial adjectives also follow central adjectives:
Sequence (4): CENTRAL -- PARTICIPIAL -- DENOMINAL -- NOUN

expensive carved Russian dolls
heavy knitted woollen clothes
huge dancing polar bears
(1) - (4) account for many sequences of up to three adjectives, in which each adjective is a different type. In practice it is rare to find more than three attributive adjectives together, especially if they are all different types. However, such a sequence may occur:

certain expensive green Russian dolls
Here the sequence is:
Sequence (5): NON-GRADABLE -- CENTRAL -- COLOUR -- DENOMINAL -- NOUN
Non-gradable adjectives, in fact, are always first in an adjective sequence. Here are some more examples:
Sequence (5a): NON-GRADABLE -- CENTRAL -- NOUN

certain difficult problems
Sequence (5b): NON-GRADABLE -- PARTICIPIAL -- NOUN

sheer unadulterated nonsense
Sequence (5c): NON-GRADABLE -- DENOMINAL -- NOUN

major medical advances
So far we have looked at sequences in which each adjective is a different type. However, we very often find adjectives of the same type occurring together:

big old buildings
beautiful little flowers
rich young people
Here all the adjectives are central adjectives, and in sequences like these it is much more difficult to determine the general principles governing their order. Several schemes have been proposed, though none is completely satisfactory or comprehensive.
The ordering of adjectives is influenced to some degree by the presence of premodification. If one or more of the adjectives in a sequence is premodified, say, by very, then it generally comes at the start of the sequence.

The laryngograph provides us with a very accurate non-invasive physical measure of voice [S2A-056-95]
It would be unusual, perhaps, to find very accurate elsewhere in this sequence:

?The laryngograph provides us with a non-invasive very accurate physical measure of voice
?The laryngograph provides us with a non-invasive physical very accurate measure of voice
Conversely, adjective order restricts the degree to which attributive adjectives may be premodified. Consider the following:

a wealthy young businessman
a very wealthy young businessman
We cannot modify young in this example, while keeping wealthy and young in the same relative order:

*a wealthy very young businessman
Nor can we move young to the first position and modify it there, while retaining the same degree of acceptability:

?a very young wealthy businessman

6 Adverbs

Adverbs are used to modify a verb, an adjective, or another adverb:
[1] Mary sings beautifully
[2] David is extremely clever
[3] This car goes incredibly fast
In [1], the adverb beautifully tells us how Mary sings. In [2], extremely tells us the degree to which David is clever. Finally, in [3], the adverb incredibly tells us how fast the car goes.
Before discussing the meaning of adverbs, however, we will identify some of their formal characteristics.
6.1 Formal Characteristics of Adverbs
From our examples above, you can see that many adverbs end in -ly. More precisely, they are formed by adding -ly to an adjective:


Adjective slow quick soft sudden gradual
Adverb slowly quickly softly suddenly gradually

Because of their distinctive endings, these adverbs are known as -LY ADVERBS. However, by no means all adverbs end in -ly. Note also that some adjectives also end in -ly, including costly, deadly, friendly, kindly, likely, lively, manly, and timely.
Like adjectives, many adverbs are GRADABLE, that is, we can modify them using very or extremely:


softly very softly
suddenly very suddenly
slowly extremely slowly

The modifying words very and extremely are themselves adverbs. They are called DEGREE ADVERBS because they specify the degree to which an adjective or another adverb applies. Degree adverbs include almost, barely, entirely, highly, quite, slightly, totally, and utterly. Degree adverbs are not gradable (*extremely very).
Like adjectives, too, some adverbs can take COMPARATIVE and SUPERLATIVE forms, with -er and -est:

John works hard -- Mary works harder -- I work hardest
However, the majority of adverbs do not take these endings. Instead, they form the comparative using more and the superlative using most:


Adverb Comparative Superlative
recently more recently most recently
effectively more effectively most effectively
frequently more frequently most frequently

In the formation of comparatives and superlatives, some adverbs are irregular:


Adverb Comparative Superlative
well better best
badly worse worst
little less least
much more most
6.2 Adverbs and Adjectives
Adverbs and adjectives have important characteristics in common -- in particular their gradability, and the fact that they have comparative and superlative forms. However, an important distinguishing feature is that adverbs do not modify nouns, either attributively or predicatively:


Adjective Adverb
David is a happy child *David is a happily child
David is happy *David is happily

The following words, together with their comparative and superlative forms, can be both adverbs and adjectives:
early, far, fast, hard, late
The following sentences illustrate the two uses of early:


Adjective Adverb
I'll catch the early train I awoke early this morning

The comparative better and the superlative best, as well as some words denoting time intervals (daily, weekly, monthly), can also be adverbs or adjectives, depending on how they are used.
We have incorporated some of these words into the following exercise. See if you can distinguish between the adverbs and the adjectives.
Although endings, gradability and comparison allow us to identify many adverbs, there still remains a very large number of them which cannot be identified in this way. In fact, taken as a whole, the adverb class is the most diverse of all the word classes, and its members exhibit a very wide range of forms and functions. Many semantic classifications of adverbs have been made, but here we will concentrate on just three of the most distinctive classes, known collectively as circumstantial adverbs.

6.3 Circumstantial Adverbs
Many adverbs convey information about the manner, time, or place of an event or action. MANNER adverbs tell us how an action is or should be performed:

She sang loudly in the bath
The sky quickly grew dark
They whispered softly
I had to run fast to catch the bus
TIME adverbs denote not only specific times but also frequency:

I'll be checking out tomorrow
Give it back, now!
John rarely rings any more
I watch television sometimes
And finally, PLACE adverbs indicate where:

Put the box there, on the table
I've left my gloves somewhere
These three adverb types -- manner, time, and place -- are collectively known as CIRCUMSTANTIAL ADVERBS. They express one of the circumstances relating to an event or action - how it happened (manner), when it happened (time), or where it happened (place).
6.4 Additives, Exclusives, and Particularizers
Additives "add" two or more items together, emphasizing that they are all to be considered equal:
[1] Lynn's prewar success had been as a light historical novelist; he employed similar fanciful ideas in his war novels [...] Joseph Hocking's war novels are also dominated by romance and adventure [W2A-009-40ff]

[2] German firms have an existing advantage as a greater number of their managers have technical or engineering degrees. Japanese managers, too, have technical qualifications of a high order. [W2A-011-51ff]
In [1], the adverb also points to the similarities between the war novels of Lynn and those of Hocking. In [2], the adverb too functions in a similar way, emphasizing the fact that the qualifications of Japanese managers are similar to those of German managers.
In contrast with additives, EXCLUSIVE adverbs focus attention on what follows them, to the exclusion of all other possibilities:
[3] It's just a question of how we organise it [S1B-075-68]

[4] The federal convention [...] comes together solely for the purpose of electing the president [S2B-021-99]
In [3], just excludes all other potential questions from consideration, while in [4], solely points out the fact that the federal convention has no other function apart from electing the president. Other exclusives include alone, exactly, merely, and simply.
PARTICULARIZERS also focus attention on what follows them, but they do not exclude other possibilities:
[5] The pastoralists are particularly found in Africa [S2A-047-3]

[6] Now this book is mostly about what they call modulation [S1A-045-167]
In [5], it is implied that Africa is not the only place where pastoralists live. While most of them live there, some of them live elsewhere. Sentence [6] implies that most of the book is about modulation, though it deals with other, unspecified topics as well.
Other particularizers include largely, mainly, primarily, and predominantly.
6.5 Wh- Adverbs
A special subclass of adverbs includes a set of words beginning with wh-. The most common are when, where, and why, though the set also includes whence, whereby, wherein, and whereupon. To this set we add the word how, and we refer to the whole set as WH- ADVERBS. Some members of the set can introduce an interrogative sentence:

When are you going to New York?
Where did you leave the car?
Why did he resign?
How did you become interested in theatre?
They can also introduce various types of clause:

This is the town where Shakespeare was born
I've no idea how it works

6.6 Sentence Adverbs
We conclude by looking at a set of adverbs which qualify a whole sentence, and not just a part of it. Consider the following:

Honestly, it doesn't matter
Here the sentence adverb honestly modifies the whole sentence, and it expresses the speaker's opinion about what is being said (When I say it doesn't matter, I am speaking honestly). Here are some more examples:

Clearly, he has no excuse for such behaviour
Frankly, I don't care about your problems
Unfortunately, no refunds can be given
Some sentence adverbs link a sentence with a preceding one:

England played well in the first half. However, in the second half their weaknesses were revealed.
Other sentence adverbs of this type are accordingly, consequently, hence, moreover, similarly, and therefore.

7 Prepositions

Prepositions cannot be distinguished by any formal features. A list of prepositions will illustrate this point:

across, after, at, before, by, during, from, in, into, of, on, to, under, with, without
We can, say, however, that prepositions typically come before a noun:


across town
after class
at home
before Tuesday
by Shakespeare for lunch
in London
on fire
to school
with pleasure

The noun does not necessarily come immediately after the preposition, however, since determiners and adjectives can intervene:

after the storm
on white horses
under the old regime
Whether or not there are any intervening determiners or adjectives, prepositions are almost always followed by a noun. In fact, this is so typical of prepositions that if they are not followed by a noun, we call them "stranded" prepositions:


Preposition Stranded Preposition
John talked about the new film This is the film John talked about

Prepositions are invariable in their form, that is, they do not take any inflections.
7.1 Complex Prepositions
The prepositions which we have looked at so far have all consisted of a single word, such as in, of, at, and to. We refer to these as SIMPLE PREPOSITIONS.
COMPLEX PREPOSITIONS consist of two- or three-word combinations acting as a single unit. Here are some examples:
according to
along with
apart from
because of
contrary to due to
except for
instead of
prior to
regardless of
Like simple prepositions, these two-word combinations come before a noun:
according to Shakespeare
contrary to my advice
due to illness
Three-word combinations often have the following pattern:

Simple Preposition + Noun + Simple Preposition
We can see this pattern in the following examples:
in aid of
on behalf of
in front of
in accordance with
in line with in line with
in relation to
with reference to
with respect to
by means of
Again, these combinations come before a noun:
in aid of charity
in front of the window
in line with inflation
7.2 Marginal Prepositions
A number of prepositions have affinities with other word classes. In particular, some prepositions are verbal in form:
Following his resignation, the minister moved to the country
I am writing to you regarding your overdraft
The whole team was there, including John
We refer to these as MARGINAL PREPOSITIONS. Other marginal prepositions include:
concerning, considering, excluding, given, granted, pending
Non-verbal marginal prepositions include worth (it's worth ten pounds) and minus (ten minus two is eight).
8 Conjunctions
Conjunctions are used to express a connection between words. The most familiar conjunctions are and, but, and or:

Paul and David
cold and wet
tired but happy
slowly but surely
tea or coffee
hot or cold
They can also connect longer units:

Paul plays football and David plays chess
I play tennis but I don't play well
We can eat now or we can wait till later
There are two types of conjunctions. COORDINATING CONJUNCTIONS (or simply COORDINATORS) connect elements of `equal' syntactic status:

Paul and David
I play tennis but I don't play well
meat or fish
Items which are connected by a coordinator are known as CONJOINS. So in I play tennis but I don't play well, the conjoins are [I play tennis] and [ I don't play well].
On the other hand, SUBORDINATING CONJUNCTIONS (or SUBORDINATORS) connect elements of `unequal' syntactic status:

I left early because I had an interview the next day
We visited Madame Tussaud's while we were in London
I'll be home at nine if I can get a taxi
Other subordinating conjunctions include although, because, before, since, till, unless, whereas, whether
Coordination and subordination are quite distinct concepts in grammar. Notice, for example, that coordinators must appear between the conjoins:

[Paul plays football] and [David plays chess]
~*And [David plays chess] [Paul plays football]
However, we can reverse the order of the conjoins, provided we keep the coordinator between them:

[David plays chess] and [Paul plays football]
In contrast with this, subordinators do not have to occur between the items they connect::

I left early because I had an interview the next day
~Because I had an interview the next day, I left early
But if we reverse the order of the items, we either change the meaning completely:

I left early because I had an interview the next day
~I had an interview the next day because I left early

or we produce a very dubious sentence:

I'll be home at nine if I can get a taxi
~?I can get a taxi if I'll be home at nine
This shows that items linked by a subordinator have a very specific relationship to each other -- it is a relationship of syntactic dependency. There is no syntactic dependency in the relationship between conjoins. We will further explore this topic when we look at the grammar of clauses.
8.1 Coordination Types
Conjoins are usually coordinated using one of the coordinators and, but, or or. In [1], the bracketed conjoins are coordinated using and:
[1] [Quickly] and [resolutely], he strode into the bank
This type of coordination, with a coordinator present, is called SYNDETIC COORDINATION.
Coordination can also occur without the presence of a coordinator, as in [2]:
[2] [Quickly], [resolutely], he strode into the bank
No coordinator is present here, but the conjoins are still coordinated. This is known as ASYNDETIC COORDINATION.
When three or more conjoins are coordinated, a coordinator will usually appear between the final two conjoins only:
[3] I need [bread], [cheese], [eggs], and [milk]
This is syndetic coordination, since a coordinating conjunction is present. It would be unusual to find a coordinator between each conjoin:
[3a] I need [bread] and [cheese] and [eggs] and [milk]
This is called POLYSYNDETIC COORDINATION. It is sometimes used for effect, for instance to express continuation:
[4] This play will [run] and [run] and [run]
[5] He just [talks] and [talks] and [talks]
8.2 False Coordination
Coordinators are sometimes used without performing any strictly coordinating role:

I'll come when I'm good and ready
Here, the adjectives good and ready are not really being coordinated with each other. If they were, the sentence would mean something like:

I'll come [when I'm good] and [when I'm ready]
Clearly, this is not the meaning which good and ready conveys. Instead, good and intensifies the meaning of ready. We might rephrase the sentence as

I'll come when I'm completely ready.
Good and ready is an example of FALSE COORDINATION -- using a coordinator without any coordinating role. It is sometimes called PSEUDO-COORDINATION.
False coordination can also be found in informal expressions using try and:

Please try and come early
I'll try and ring you from the office
Here, too, no real coordination is taking place. The first sentence, for instance, does not mean Please try, and please come early. Instead, it is semantically equivalent to Please try to come early.
In informal spoken English, and and but are often used as false coordinators, without any real coordinating role. The following extract from a conversation illustrates this:

Speaker A: Well he told me it's this super high-flying computer software stuff. I'm sure it's the old job he used to have cleaning them

Speaker B: But it went off okay last night then did it? Did you have a good turnout? [S1A-005-95ff]
Here, the word but used by Speaker B does not coordinate any conjoins. Instead, it initiates her utterance, and introduces a completely new topic.

9 Minor word classes

We have now looked at the seven major word classes in English. Most words can be assigned to at least one of these classes. However, there are some words which will not fit the criteria for any of them. Consider, for example, the word hello. It is clearly not a noun, or an adjective, or a verb, or indeed any of the classes we have looked at. It belongs to a minor word class, which we call formulaic expressions.

9.1 Formulaic Expressions
To express greetings, farewell, thanks, or apologies, we use a wide range of FORMULAIC EXPRESSIONS. These may consist of a single word or of several words acting as a unit. Here are some examples:

bye
goodbye
hello
farewell
hi
so long excuse me
thanks
thank you
thanks a lot
sorry
pardon

Some formulaic expressions express agreement or disagreement with a previous speaker:
yes, yeah, no, okay, right, sure
INTERJECTIONS generally occur only in spoken English, or in the representation of speech in novels. They include the following:
ah, eh, hmm, oh, ouch, phew, shit, tsk, uhm, yuk
Interjections express a wide range of emotions, including surprise (oh!), exasperation (shit!), and disgust (yuk!).
Formulaic expressions, including interjections, are unvarying in their form, that is, they do not take any inflections.
9.2 Existential there
We have seen that the word there is an adverb, in sentences such as:
You can't park there
I went there last year
Specifically, it is an adverb of place in these examples.
However, the word there has another use. As EXISTENTIAL THERE, it often comes at the start of a sentence:
There is a fly in my soup
There were six errors in your essay
Existential there is most commonly followed by a form of the verb be. When it is used in a question, it follows the verb:
Is there a problem with your car?
Was there a storm last night?
The two uses of there can occur in the same sentence:
There is a parking space there
In this example, the first there is existential there, and the second is an adverb.
9.3 Uses of It
In the section on pronouns, we saw that the word it is a third person singular pronoun. However, this word also has other roles which are not related to its pronominal use. We look at some of these other uses here.
When we talk about time or the weather, we use sentences such as:
What time is it?
It is four o'clock
It is snowing
It's going to rain
Here, we cannot identify precisely what it refers to. It has a rather vague reference, and we call this DUMMY IT or PROP IT. Dummy it is also used, equally vaguely, in other expressions:
Hold it!
Take it easy!
Can you make it to my party?
It is sometimes used to "anticipate" something which appears later in the same sentence:
It's great to see you
It's a pity you can't come to my party
In the first example, it "anticipates" to see you. We can remove it from the sentence and replace it with to see you:
To see you is great
Because of its role in this type of sentence, we call this ANTICIPATORY IT.

10 Introduces phrases

We have now completed the first level of grammatical analysis, in which we looked at words individually and classified them according to certain criteria. This classification is important because, as we'll see, it forms the basis of the next level of analysis, in which we consider units which may be larger than individual words, but are smaller than sentences. In this section we will be looking at PHRASES.
10.1 Defining a Phrase
When we looked at nouns and pronouns, we said that a pronoun can sometimes replace a noun in a sentence. One of the examples we used was this:
[Children] should watch less television
~[They] should watch less television
Here it is certainly true that the pronoun they replaces the noun children. But consider:
[The children] should watch less television
~[They] should watch less television
In this example, they does not replace children. Instead, it replaces the children, which is a unit consisting of a determiner and a noun. We refer to this unit as a NOUN PHRASE (NP), and we define it as any unit in which the central element is a noun. Here is another example:
I like [the title of your book]
~I like [it]
In this case, the pronoun it replaces not just a noun but a five-word noun phrase, the title of your book. So instead of saying that pronouns can replace nouns, it is more accurate to say that they can replace noun phrases.
We refer to the central element in a phrase as the HEAD of the phrase. In the noun phrase the children, the Head is children. In the noun phrase the title of your book, the Head is title.
Noun phrases do not have to contain strings of words. In fact, they can contain just one word, such as the word children in children should watch less television. This is also a phrase, though it contains only a Head. At the level of word class, of course, we would call children a plural, common noun. But in a phrase-level analysis, we call children on its own a noun phrase. This is not simply a matter of terminology -- we call it a noun phrase because it can be expanded to form longer strings which are more clearly noun phrases.
From now on in the Internet Grammar, we will be using this phrase-level terminology. Furthermore, we will delimit phrases by bracketing them, as we have done in the examples above.
10.2 The Basic Structure of a Phrase
Phrases consist minimally of a Head. This means that in a one-word phrase like [children], the Head is children. In longer phrases, a string of elements may appear before the Head:
[the small children]
For now, we will refer to this string simply as the pre-Head string.
A string of elements may also appear after the Head, and we will call this the post-Head string:
[the small children in class 5]
So we have a basic three-part structure:

pre-Head string Head post-Head string
[the small children in class 5]

Of these three parts, only the Head is obligatory. It is the only part which cannot be omitted from the phrase. To illustrate this, let's omit each part in turn:

pre-Head string Head post-Head string
[-- children in class 5]
*[the small -- in class 5]
[the small children --]

Pre-Head and post-Head strings can be omitted, while leaving a complete noun phrase. We can even omit the pre- and post-Head strings at the same time, leaving only the Head:

pre-Head string Head post-Head string
[-- children --]
This is still a complete noun phrase.
However, when the Head is omitted, we're left with an incomplete phrase (*the small in class five). This provides a useful method of identifying the Head of a phrase. In general, the Head is the only obligatory part of a phrase.
10.3 More Phrase Types
Just as a noun functions as the Head of a noun phrase, a verb functions as the Head of a verb phrase, and an adjective functions as the Head of an adjective phrase, and so on. We recognise five phrase types in all:

Phrase Type Head Example
Noun Phrase Noun [the children in class 5]
Verb Phrase Verb [play the piano]
Adjective Phrase Adjective [delighted to meet you]
Adverb Phrase Adverb [very quickly]
Prepositional Phrase Preposition [in the garden]

For convenience, we will use the following abbreviations for the phrase types:

Phrase Type Abbreviation
Noun Phrase NP
Verb Phrase VP
Adjective Phrase AP
Adverb Phrase AdvP
Prepositional Phrase PP

Using these abbreviations, we can now label phrases as well as bracket them. We do this by putting the appropriate label inside the opening bracket:
[NP the small children in class 5]
Now we will say a little more about each of the five phrase types.
10.4 Noun Phrase (NP)
As we've seen, a noun phrase has a noun as its Head. Determiners and adjective phrases usually constitute the pre-Head string:
[NP the children]
[NP happy children]
[NP the happy children]
In theory at least, the post-Head string in an NP can be indefinitely long:
[NP the dog that chased the cat that killed the mouse that ate the cheese that was made from the milk that came from the cow that...]
Fortunately, they are rarely as long as this in real use.
The Head of an NP does not have to be a common or a proper noun. Recall that pronouns are a subclass of nouns. This means that pronouns, too, can function as the Head of an NP:
[NP I] like coffee
The waitress gave [NP me] the wrong dessert
[NP This] is my car
If the Head is a pronoun, the NP will generally consist of the Head only. This is because pronouns do not take determiners or adjectives, so there will be no pre-Head string. However, with some pronouns, there may be a post-Head string:
[NP Those who arrive late] cannot be admitted until the interval
Similarly, numerals, as a subclass of nouns, can be the Head of an NP:
[NP Two of my guests] have arrived
[NP The first to arrive] was John
10.5 Verb Phrase (VP)
In a VERB PHRASE (VP), the Head is always a verb. The pre-Head string, if any, will be a `negative' word such as not [1] or never [2], or an adverb phrase [3]:
[1] [VP not compose an aria]
[2] [VP never compose an aria]
[3] Paul [VP deliberately broke the window]
Many verb Heads must be followed by a post-Head string:
My son [VP made a cake] -- (compare: *My son made)
We [VP keep pigeons] -- (compare: *We keep)
I [VP recommend the fish] -- (compare: *I recommend)
Verbs which require a post-Head string are called TRANSITIVE verbs. The post-Head string, in these examples, is called the DIRECT OBJECT.
In contrast, some verbs are never followed by a direct object:
Susan [VP smiled]
The professor [VP yawned]
These are known as INTRANSITIVE VERBS.
However, most verbs in English can be both transitive and intransitive, so it is perhaps more accurate to refer to transitive and intransitive uses of a verb. The following examples show the two uses of the same verb:
Intransitive: David smokes
Transitive: David smokes cigars
We will return to the structure of verb phrases in a later section.
10.6 Adjective Phrase (AP)
In an ADJECTIVE PHRASE (AP), the Head word is an adjective. Here are some examples:
Susan is [AP clever]
The doctor is [AP very late]
My sister is [AP fond of animals]
The pre-Head string in an AP is most commonly an adverb phrase such as very or extremely. Adjective Heads may be followed by a post-Head string:
[AP happy to meet you]
[AP ready to go]
[AP afraid of the dark]
A small number of adjective Heads must be followed by a post-Head string. The adjective Head fond is one of these. Compare:
My sister is [AP fond of animals]
*My sister is [fond]
10.7 Adverb Phrase (AdvP)
In an ADVERB PHRASE, the Head word is an adverb. Most commonly, the pre-Head string is another adverb phrase:
He graduated [AdvP very recently]
She left [AdvP quite suddenly]
In AdvPs, there is usually no post-Head string, but here's a rare example:
[AdvP Unfortunately for him], his wife came home early
10.8 Prepositional Phrase (PP)
PREPOSITIONAL PHRASES usually consist of a Head -- a preposition -- and a post-Head string only. Here are some examples:
[PP through the window]
[PP over the bar]
[PP across the line]
[PP after midnight]
This makes PPs easy to recognise -- they nearly always begin with a preposition (the Head). A pre-Head string is rarely present, but here are some examples:
[PP straight through the window]
[PP right over the bar]
[PP just after midnight]
10.9 Phrases within Phrases
We will conclude this introduction to phrases by looking briefly at phrases within phrases. Consider the NP:
[NP small children]
It consists of a Head children and a pre-Head string small. Now small is an adjective, so it is the Head of its own adjective phrase. We know this because it could be expanded to form a longer string:
very small children
Here, the adjective Head small has its own pre-Head string very:
[AP very small]
So in small children, we have an AP small embedded with the NP small children. We represent this as follows:
[NP [AP small] children]
All but the simplest phrases will contain smaller phrases within them. Here's another example:
[PP across the road]
Here, the Head is across, and the post-Head string is the road. Now we know that the road is itself an NP -- its Head is road, and it has a pre-Head string the. So we have an NP within the PP:
[PP across [NP the road]]
When you examine phrases, remember to look out for other phrases within them.
11 Clauses and sentences

So far we have been looking at phrases more or less in isolation. In real use, of course, they occur in isolation only in very restricted circumstances. For example, we find isolated NPs in public signs and notices:
[Exit]
[Sale]
[Restricted Area]
[Hyde Park]
We sometimes use isolated phrases in spoken English, especially in responses to questions:
Q: What would you like to drink?
A: [NP Coffee]
Q: How are you today?
A: [AP Fine]
Q: Where did you park the car?
A: [PP Behind the house]
In more general use, however, phrases are integrated into longer units, which we call CLAUSES:
Q: What would you like to drink?
A: [I'd like coffee]
Q: How are you today?
A: [I'm fine]
Q: Where did you park the car?
A: [I parked the car behind the house]
11.1 The Clause Hierarchy
The clause I'd like coffee is a SUBORDINATE CLAUSE within the sentence I think I'd like coffee. We refer to this larger clause as the MATRIX CLAUSE:

The matrix clause is not subordinate to any other, so it is, in fact, co-extensive with the sentence.
We say that the matrix clause is SUPERORDINATE to the subordinate clause.
The terms subordinate and superordinate are relative terms. They describe the relationship between clauses in what is called the CLAUSE HIERARCHY. We can illustrate what this means by looking at a slightly more complicated example:
He said I think I'd like coffee
Here the matrix clause is:
He said I think I'd like coffee
This matrix clause contains two subordinate clauses, which we'll refer to as Sub1 and Sub2:

Sub1 is both subordinate and superordinate. It is subordinate in relation to the matrix clause, and it is superordinate in relation to Sub2.
Subordinate and superordinate, then, are not absolute terms. They describe how clauses are arranged hierarchically relative to each other.
We can bracket and label clauses in the same way as phrases. We will use the following abbreviations:
Matrix Clause: MC
Subordinate Clause: SubC
Applying these labels and brackets to our first example, we get:
[MC I think [SubC I'd like coffee]]
Just as we've seen with phrases, we can have embedding in clauses too. Here, the subordinate clause is embedded within the matrix clause.
There is a greater degree of embedding in our second example, where there are two subordinate clauses, one within the other:
[MC He said [SubC I think [SubC I'd like coffee]]]
11.2 Finite and Nonfinite Clauses
As a working definition, let us say that clauses contain at least a verb phrase:
[MC [VP Stop]]
[MC David [VP composed an aria] when he was twelve]
[MC My solicitor [VP sent me a letter] yesterday]
As these examples show, clauses can also contain many other elements, but for now we will concentrate on the VP. We have already seen that verbs (and therefore the VPs that contain them) are either FINITE or NONFINITE, so we can use this distinction to classify clauses. Clauses are either finite or nonfinite.
Finite verb phrases carry tense, and the clauses containing them are FINITE CLAUSES:
[1] She writes home every day (finite clause -- present tense verb)
[2] She wrote home yesterday (finite clause -- past tense verb)
On the other hand, nonfinite verb phrases do not carry tense. Their main verb is either a to-infinitive [3], a bare infinitive [4], an -ed form [5], or an -ing form [6]:
[3] David loves [to play the piano]
[4] We made [David play the piano]
[5] [Written in 1864], it soon became a classic
[6] [Leaving home] can be very traumatic
These are NONFINITE CLAUSES.
Matrix clauses are always finite, as in [1] and [2]. However, they may contain nonfinite subordinate clauses within them. For example:
[MC David loves [SubC to play the piano]]
Here we have a finite matrix clause -- its main verb loves has the present tense form. Within it, there is a nonfinite subordinate clause to play the piano -- its main verb play has the to-infinitive form.
On the other hand, subordinate clauses can be either finite or nonfinite:
Finite: He said [SubC that they stayed at a lovely hotel] -- past tense
Nonfinite: I was advised [SubC to sell my old car] -- to-infinitive
11.3 Subordinate Clause Types
Subordinate clauses may be finite or nonfinite. Within this broad classification, we can make many further distinctions. We will begin by looking at subordinate clauses which are distinguished by their formal characteristics.
Many subordinate clauses are named after the form of the verb which they contain:
TO-INFINITIVE CLAUSE:

You must book early [to secure a seat]
BARE INFINITIVE CLAUSE:

They made [the professor forget his notes]
-ING PARTICIPLE CLAUSE:

His hobby is [collecting old photographs]
-ED PARTICIPLE CLAUSE:

[Rejected by his parents], the boy turned to a life of crime
For convenience, we sometimes name a clause after its first element:
IF-CLAUSE:

I'll be there at nine [if I catch the early train]
As we'll see on the next page, if-clauses are sometimes called conditional clauses.
THAT-CLAUSE:

David thinks [that we should have a meeting]
The that element is sometimes ellipted:
David thinks [we should have a meeting]
11.3.1 Relative Clauses
An important type of subordinate clause is the RELATIVE CLAUSE. Here are some examples:
The man [who lives beside us] is ill
The video [which you recommended] was terrific
Relative clauses are generally introduced by a relative pronoun, such as who, or which. However, the relative pronoun may be ellipted:
The video [you recommended] was terrific
Another variant, the REDUCED RELATIVE CLAUSE, has no relative pronoun, and the verb is nonfinite:
The man [living beside us] is ill
(Compare: The man [who lives beside us]...)
11.3.2 Nominal Relative Clauses
NOMINAL RELATIVE CLAUSES (or independent relatives) function in some respects like noun phrases:
[What I like best] is football
(cf. the sport I like best...)
The prize will go to [whoever submits the best design]
(cf. the person who submits...)
My son is teaching me [how to use email]
(cf. the way to use email)
This is [where Shakespeare was born]
(cf. the place where...)
The similarity with NPs can be further seen in the fact that certain nominal relatives exhibit number contrast:
Singular: [What we need] is a plan
Plural: [What we need] are new ideas
Notice the agreement here with is (singular) and are (plural).
11.3.3 Small Clauses
Finally, we will mention briefly an unusual type of clause, the verbless or SMALL CLAUSE. While clauses usually contain a verb, which is finite or nonfinite, small clauses lack an overt verb:
Susan found [the job very difficult]
We analyse this as a unit because clearly its parts cannot be separated. What Susan found was not the job, but the job very difficult. And we analyse this unit specifically as a clause because we can posit an implicit verb, namely, a form of the verb be:
Susan found [the job (to be) very difficult]
Here are some more examples of small clauses:
Susan considers [David an idiot]
The jury found [the defendant guilty]
[Lunch over], the guests departed quickly
All of the clause types discussed here are distinguished by formal characteristics. On the next page, we will distinguish some more types, this time on the basis of their meaning.
11.4 Subordinate Clauses: Semantic Types
Here we will look at subordinate clauses from the point of view of their meaning. The main semantic types are exemplified in the following table:
Subordinate Clause Type Example
Temporal I'll ring you again [before I leave]

David joined the army [after he graduated]

[When you leave], please close the door

I read the newspaper [while I was waiting]
Conditional I'll be there at nine [if I can catch the early train]

[Provided he works hard], he'll do very well at school

Don't call me [unless its an emergency]
Concessive He bought me a lovely gift, [although he can't really afford it]

[Even though he worked hard], he failed the final exam

[While I don't agree with her], I can understand her viewpoint
Reason Paul was an hour late [because he missed the train]

I borrowed your lawn mower, [since you weren't using it]

[As I don't know the way], I'll take a taxi
Result The kitchen was flooded, [so we had to go to a restaurant]

I've forgotten my password, [so I can't read my email]
Comparative This is a lot more difficult [than I expected]

She earns as much money [as I do]

I think London is less crowded [than it used to be]
The table does not cover all the possible types, but it does illustrate many of the various meanings which can be expressed by subordinate clauses.
Notice that the same word can introduce different semantic types. For instance, the word while can introduce a temporal clause:
I read the newspaper [while I was waiting]
or a concessive clause:
[While I don't agree with her], I can understand her viewpoint.
Similarly, the word since can express time:
I've known him [since he was a child]
as well as reason:
I borrowed your lawn mower, [since you weren't using it]
In the following exercise, be aware of words like these, which can introduce more than one type of subordinate clause.
11.5 Sentences
Most people recognise a sentence as a unit which begins with a capital letter and ends with a full stop (period), a question mark, or an exclamation mark. Of course, this applies only to written sentences. Sentences have also been defined notionally as units which express a "complete thought", though it is not at all clear what a "complete thought" is.
It is more useful to define a sentence syntactically, as a unit which consists of one or more clauses. According to this definition, the following examples are all sentences:
[1] Paul likes football
[2] You can borrow my pen if you need one
[3] Paul likes football and David likes chess
Sentence [1] is a SIMPLE SENTENCE -- it contains only one clause.
Sentence [2] consists of a matrix clause You can borrow my pen if you need one, and a subordinate clause if you need one. This is called a COMPLEX SENTENCE. A complex sentence is defined as a sentence which contains at least one subordinate clause.
Finally, sentence [3] consists of two clauses which are coordinated with each other. This is a COMPOUND sentence.
By using subordination and coordination, sentences can potentially be infinitely long, but in all cases we can analyse them as one or more clauses.
11.6 The Discourse Functions of Sentences
Sentences may be classified according to their use in discourse. We recognise four main sentence types:
• declarative
• interrogative
• imperative
• exclamative
11.6.1 Declarative
Declarative sentences are used to convey information or to make statements:
David plays the piano
I hope you can come tomorrow
We've forgotten the milk
Declarative sentences are by far the most common type.
11.6.2 Interrogative
Interrogative sentences are used in asking questions:
Is this your book?
Did you receive my message?
Have you found a new job yet?
The examples above are specifically YES/NO INTERROGATIVES, because they elicit a response which is either yes or no.
ALTERNATIVE INTERROGATIVES offer two or more alternative responses:
Should I telephone you or send an email?
Do you want tea, coffee, or espresso?
Yes/no interrogatives and alternative interrogatives are introduced by an auxiliary verb.
WH- INTERROGATIVES, on the other hand, are introduced by a wh- word, and they elicit an open-ended response:
What happened?
Where do you work?
Who won the Cup Final in 1997?
Questions are sometimes tagged onto the end of a declarative sentence:
David plays the piano, doesn't he?
We've forgotten the milk, haven't we?
There's a big match tonight, isn't there?
These are known as TAG QUESTIONS. They consist of a main or auxiliary verb followed by a pronoun or existential there
11.6.3 Imperative
Imperative sentences are used in issuing orders or directives:
Leave your coat in the hall
Give me your phone number
Don't shut the door
Stop!
Tag questions are sometimes added to the end of imperatives:
Leave your coat in the hall, will you?
Write soon, won't you?
In an imperative sentence, the main verb is in the base form. This is an exception to the general rule that matrix clauses are always finite.
11.6.4 Exclamative
Exclamative sentences are used to make exclamations:
What a stupid man he is!
How wonderful you look!
The four sentence types exhibit different syntactic forms, which we will be looking at in a later section. For now, it is worth pointing out that there is not necessarily a one-to-one relationship between the form of a sentence and its discourse function. For instance, the following sentence has declarative form:
You need some help
But when this is spoken with a rising intonation, it becomes a question:
You need some help?
Conversely, rhetorical questions have the form of an interrogative, but they are really statements:
Who cares? ( = I don't care)
11.7 The Grammatical Hierarchy: Words, Phrases, Clauses, and Sentences
Words, phrases, clauses, and sentences constitute what is called the GRAMMATICAL HIERARCHY. We can represent this schematically as follows:
sentences
consist of one or more...
clauses
consist of one or more...
phrases
consist of one or more...
words
Sentences are at the top of the hierarchy, so they are the largest unit which we will be considering (though some grammars do look beyond the sentence). At the other end of the hierarchy, words are at the lowest level, though again, some grammars go below the word to consider morphology, the study of how words are constructed.
At the clause level and at the phrase level, two points should be noted:
1. Although clauses are higher than phrases in the hierarchy, clauses can occur within phrases, as we've already seen:
The man who lives beside us is ill
Here we have a relative clause who lives beside us within the NP the man who lives beside us.
2. We've also seen that clauses can occur within clauses, and phrases can occur within phrases.
Bearing these two points in mind, we can now illustrate the grammatical hierarchy using the following sentence:
My brother won the lottery
As a means of illustrating the grammatical hierarchy, the labelled brackets we have used here have at least one major drawback. You've probably noticed it already -- they are very difficult to interpret. And the problem becomes more acute as the sentence becomes more complex. For this reason, linguists prefer to employ a more visual method, the TREE DIAGRAM.
12 Form and Function
We have used the word "form" quite often in the Internet Grammar. It was one of the criteria we used to distinguish between word classes -- we saw that the form or "shape" of a word is often a good clue to its word class.
When we looked at phrases, too, we were concerned with their form. We said that phrases may have the basic form (Pre-Head string) - Head - (Post-Head string).
And finally, we classified clauses according to the form (finite or nonfinite) of their main verb.
In all of these cases, we were conducting a FORMAL analysis. Form denotes how something looks -- its shape or appearance, and what its structure is. When we say that the old man is an NP, or that the old man bought a newspaper is a finite clause, we are carrying out a formal analysis.
We can also look at constituents -- phrases and clauses -- from another angle. We can examine the FUNCTIONs which they perform in the larger structures which contain them.
12.1 Subject and Predicat
The most familiar grammatical function is the SUBJECT. In notional terms, we can think of the Subject as the element which performs the "action" denoted by the verb:
[1] David plays the piano
[2] The police interviewed all the witnesses
In [1], the Subject David performs the action of playing the piano. In [2], the Subject the police performs the action of interviewing all the witnesses. In these terms, this means that we can identify the Subject by asking a wh-question:
[1] David plays the piano
Q. Who plays the piano?
A. David ( = Subject)
[2] The police interviewed all the witnesses
Q. Who interviewed all the witnesses?
A. The police (= Subject)
Having identified the Subject, we can see that the remainder of the sentence tells us what the Subject does or did. In [1], for example, plays the piano tells us what David does. We refer to this string as the PREDICATE of the sentence. In [2], the Predicate is interviewed all the witnesses.
Here are some more examples of sentences labelled for Subject and Predicate.

Subject Predicate
The lion roared
He writes well
She enjoys going to the cinema
The girl in the blue dress arrived late

In each of these examples, the Subject performs the action described in the Predicate. We've seen, however, that there are problems in defining verbs as "action" words, and for the same reasons, there are problems in defining the Subject as the "performer" of the action. The Subject in John seems unhappy is John, but we would hardly say he is performing an action. For this reason, we need to define the Subject more precisely than this. We will look at the characteristics of the Subject on the next page.
12.2 Characteristics of the Subject
The grammatical Subject has a number of characteristics which we will examine here.

1. Subject-Verb Inversion
In a declarative sentence, the Subject comes before the verb:
Declarative: David is unwell
When we change this into a yes/no interrogative, the Subject and the verb change places with each other:
If an auxiliary verb is present, however, the Subject changes places with the auxiliary:
Declarative: Jim has left already
Interrogative: Has Jim left already?
In this interrogative, the Subject still comes before the main verb, but after the auxiliary. This is true also of interrogatives with a do-auxiliary:
Declarative: Jim left early
Interrogative: Did Jim leave early?
Subject-verb inversion is probably the most reliable method of identifying the Subject of a sentence.

2. Position of the Subject
In a declarative sentence, the Subject is usually the first constituent:
Jim was in bed
Paul arrived too late for the party
The Mayor of New York attended the banquet
We made a donation to charity
However, there are exceptions to this. For instance:
Yesterday the theatre was closed
Here, the first constituent is the adverb phrase yesterday, but this is not the Subject of the sentence. Notice that the theatre, and not yesterday, inverts with the verb in the interrogative:
Declarative: Yesterday the theatre was closed
Interrogative: Yesterday was the theatre closed?
So the Subject here is the theatre, even though it is not the first constituent in the sentence.

3. Subject-verb Agreement
Subject-verb AGREEMENT or CONCORD relates to number agreement (singular or plural) between the Subject and the verb which follows it:
Singular Subject: The dog howls all night
Plural Subject: The dogs howl all night
There are two important limitations to Subject-verb agreement. Firstly, agreement only applies when the verb is in the present tense. In the past tense, there is no overt agreement between the Subject and the verb:
The dog howled all night
The dogs howled all night
And secondly, agreement applies only to third person Subjects. There is no distinction, for example, between a first person singular Subject and a first person plural Subject:
I howl all night
We howl all night
The concept of NOTIONAL AGREEMENT sometimes comes into play:
The government is considering the proposal
The government are considering the proposal
Here, the form of the verb is not determined by the form of the Subject. Instead, it is determined by how we interpret the Subject. In the government is..., the Subject is interpreted as a unit, requiring a singular form of the verb. In the government are..., the Subject is interpreted as having a plural meaning, since it relates to a collection of individual people. Accordingly, the verb has the plural form are.

4. Subjective Pronouns
The pronouns I, he/she/it, we, they, always function as Subjects, in contrast with me, him/her, us, them:
I left early
*Me left early
He left early
*Him left early
We left early
*Us left early
They left early
*Them left early
The pronoun you can also be a Subject:
You left early
but it does not always perform this function. In the following example, the Subject is Tom, not you:
Tom likes you
12.3 Realisations of the Subject
In the sentence, Jim was in bed, the Subject is the NP Jim. More precisely, we say that the Subject is realised by the NP Jim. Conversely, the NP Jim is the realisation of the Subject in this sentence. Remember that NP is a formal term, while Subject is a functional term:
FORM FUNCTION
Noun Phrase Subject
Subjects are typically realised by NPs. This includes NPs which have pronouns [1], cardinal numerals [2], and ordinal numerals [3] as their Head word:
[1] [We] decided to have a party
[2] [One of my contacts lenses] fell on the floor
[3] [The first car to reach Brighton] is the winner
However, other constituents can also function as Subjects, and we will examine these in the following sections.
Clauses functioning as Subject
Clauses can also function as Subjects. When they perform this function, we refer to them generally as Subject clauses. The table below shows examples of the major types of Subject clauses:

CLAUSES
functioning as
SUBJECTS EXAMPLE
Finite

That-clause


Nominal Relative clause

[1] That his theory was flawed soon became obvious

[2] What I need is a long holiday
Nonfinite

To-infinitive clause


-ing clause

[3] To become an opera singer takes years of training

[4] Being the chairman is a huge responsibility
Notice that some of these Subject clauses have Subjects of their own. In [1], the Subject clause that his theory was flawed, has its own Subject, his theory. Similarly, in [2], the Subject of what I need is I.
Among nonfinite clauses, only to-infinitive clauses and -ing participle clauses can function as Subject. Bare infinitive clauses and -ed participle clauses cannot perform this function. In the examples above -- [3] and [4] -- the nonfinite Subject clauses do not have Subjects of their own, although they can do:
[3a] For Mary to become an opera singer would take years of training
[4a] David being the chairman has meant more work for all of us
Prepositional Phrases functioning as Subject
Less commonly, the Subject may be realised by a prepositional phrase:
After nine is a good time to ring
Prepositional phrases as Subject typically refer to time or to space.
12.4 Some Unusual Subjects
Before leaving this topic, we will point out some grammatical Subjects which may at first glance be difficult to recognise as such. For example, can you work out the Subject of the following sentence?
There is a fly in my soup
As we've seen, the most reliable test for identifying the Subject is Subject-verb inversion, so let's try it here:
Declarative: There is a fly in my soup
Interrogative: Is there a fly in my soup?
The inversion test shows that the subject is there. You will recall that this is an example of existential there, and the sentence in which it is the Subject is an existential sentence.
Now try the same test on the following:
It is raining
The inversion test shows that the Subject is it:
Declarative: It is raining
Interrogative: Is it raining?
These two examples illustrate how limited the notional definition of the Subject really is. In no sense can we say that there and it are performing an "action" in their respective sentences, and yet they are grammatically functioning as Subjects.
On this page, we've seen that the function of Subject can be realised by several different forms. Conversely, the various forms (NP, clause, PP, etc) can perform several other functions, and we will look at these in the following pages.
12.5 Inside the Predicate
Now we will look inside the Predicate, and assign functions to its constituents. Recall that the Predicate is everything apart from the Subject. So in David plays the piano, the Predicate is plays the piano. This Predicate consists of a verb phrase, and we can divide this into two further elements:
[plays] [the piano]
In formal terms, we refer to the verb as the PREDICATOR, because its function is to predicate or state something about the subject. Notice that Predicator is a functional term, while verb is a formal term:

FORM FUNCTION
Verb Predicator
However, since the Predicator is always realised by a verb, we will continue to use the more familiar term verb, even when we are discussing functions.
12.6 The Direct Object
In the sentence David plays the piano, the NP the piano is the constituent which undergoes the "action" of being played (by David, the Subject). We refer to this constituent as the DIRECT OBJECT.
Here are some more examples of Direct Objects:
We bought a new computer
I used to ride a motorbike
The police interviewed all the witnesses
We can usually identify the Direct Object by asking who or what was affected by the Subject. For example:
We bought a new computer
Q. What did we buy?
A. A new computer ( = the Direct Object)
The Direct Object generally comes after the verb, just as the Subject generally comes before it. So in a declarative sentence, the usual pattern is:
Subject -- Verb -- Direct Object
The following table shows more examples of this pattern:

Subject Verb Direct Object
The tourists visited the old cathedral
She sent a postcard
The detectives examined the scene of the crime
12.7 Realisations of the Direct Object
The Direct Object is most often realised by an NP, as in the examples above. However, this function can also be realised by a clause. The following table shows examples of clauses functioning as Direct Objects:

CLAUSES
functioning as
DIRECT OBJECTS EXAMPLES
Finite
That-clause
Nominal relative clause

[1] He thought that he had a perfect alibi
[2] The officer described what he saw through the keyhole
Nonfinite
To-infinitive clause
Bare infinitive clause
-ing clause
-ed clause

[3] The dog wants to play in the garden
[4] She made the lecturer laugh
[5] Paul loves playing football
[6] I'm having my house painted

12.8 Subjects and Objects, Active and Passive
A useful way to compare Subjects and Direct Objects is to observe how they behave in active and passive sentences. Consider the following active sentence:
Active: Fire destroyed the palace
Here we have a Subject fire and a Direct Object the palace.
Now let's convert this into a passive sentence:
The change from active to passive has the following results:
1. The active Direct Object the palace becomes the passive Subject

2. The active Subject fire becomes part of the PP by fire (the by-agent phrase).
12.9 The Indirect Object
Some verbs occur with two Objects:
We gave [John] [a present]
Here, the NP a present undergoes the "action" (a present is what is given). So a present is the Direct Object. We refer to the NP John as the INDIRECT OBJECT.
Indirect Objects usually occur with a Direct Object, and they always come before the Direct Object. The typical pattern is:
Subject -- Verb -- Indirect Object -- Direct Object
Here are some more examples of sentences containing two objects:

Indirect Object Direct Object
Tell me a story
He showed us his war medals
We bought David a birthday cake
Can you lend your colleague a pen?
Verbs which take an Indirect Object and a Direct Object are known as DITRANSITIVE verbs. Verbs which take only a Direct Object are called MONOTRANSITIVE verbs. The verb tell is a typical ditransitive verb, but it can also be monotransitive:

Indirect Object Direct Object
Ditransitive David told the children a story
Monotransitive David told a story
As we've seen, an Indirect Object usually co-occurs with a Direct Object. However, with some verbs an Indirect Object may occur alone:
David told the children
although we can usually posit an implicit Direct Object in such cases:
David told the children the news
12.10 Realisations of the Indirect Object
NPs are the most common realisations of the Indirect Object. It is a typical function of pronouns in the objective case, such as me, him, us, and them.
Less commonly, a clause will function as Indirect Object:
David told whoever saw her to report to the police
12.11 Adjuncts
Certain parts of a sentence may convey information about how, when, or where something happened:
He ate his meal quickly (how)
David gave blood last week (when)
Susan went to school in New York (where)
The highlighted constituents here are ADJUNCTS. From a syntactic point of view, Adjuncts are optional elements, since their omission still leaves a complete sentence:
He ate his meal quickly ~He ate his meal

David gave blood last week ~David gave blood

Susan went to school in New York ~Susan went to school
Many types of constituents can function as Adjuncts, and we exemplify these below.
12.12 Realisations of Adjuncts
Noun Phrases functioning as Adjuncts
David gave blood last week
Next summer, we're going to Spain
We've agreed to meet the day after tomorrow
NPs as Adjuncts generally refer to time, as in these examples.

Adverb Phrases functioning as Adjuncts
They ate their meal too quickly
She walked very gracefully down the steps
Suddenly, the door opened

Prepositional Phrases functioning as Adjuncts
Susan went to school in New York
I work late on Mondays
After work, I go to a local restaurant
PPs as Adjuncts generally refer to time or to place -- they tell us when or where something happens.

Clauses functioning as Adjuncts
Subordinate clauses can function as Adjuncts. We'll begin with some examples of finite subordinate clauses:

Clauses
functioning as
Adjuncts EXAMPLES
Finite While we were crossing the park, we heard a loud explosion
I was late for the interview because the train broke down
If you want tickets for the concert, you have to apply early
My car broke down, so I had to walk
Nonfinite
To-infinitive clause
Bare infinitive clause
-ing clause

-ed clause
Small clause

To open the window, you have to climb a ladder
Rather than leave the child alone, I brought him to work with me
Being a qualified plumber, Paul had no difficulty in finding the leak
Left to himself, he usually gets the job done quickly
His face red with rage, John stormed out of the room

You will notice that these clauses express the range of meanings that we looked at earlier (in Subordinate Clauses: Semantic Types). In all cases, notice also that the Adjuncts express additional and optional information. If they are omitted, the remaining clause is still syntactically complete.
12.13 Sentence Patterns from a Functional Perspective
In order to summarise what we have learned, we will now look at some typical sentence patterns from a functional perspective. We will then conclude this section by looking at some untypical patterns, on the next page.
As we've seen, the Subject is usually (but not always) the first element in a sentence, and it is followed by the verb:
Pattern 1
Subject Verb
David

The dog

Susan sings

barked

yawned
In this pattern, the verb is not followed by any Object, and we refer to this as an intransitive verb. If the verb is monotransitive, it takes a Direct Object, which follows the verb:
Pattern 2
Subject Verb Direct Object
David

The professor

The jury sings

wants

found ballads

to retire

the defendant guilty

In the ditransitive pattern, the verb is followed by an Indirect Object and a Direct Object, in that order:
Pattern 3
Subject Verb Indirect Object Direct Object
The old man

My uncle

The detectives gave

sent

asked the children

me

Amy some money

a present

lots of questions
Adjuncts are syntactically peripheral to the rest of the sentence. They may occur at the beginning and at the end of a sentence, and they may occur in all three of the patterns above:
Pattern 4
(Adjunct) Subject Verb Indirect Object Direct Object (Adjunct)
[1] Usually David sings in the bath
[2] Unfortunately the professor wants to retire this year
[3] At the start of the trial the judge showed the jury the photographs in a private chamber
Pattern 4 is essentially a conflation of the other three, with Adjuncts added. We have bracketed the Adjuncts to show that they are optional. Strictly speaking, Objects are also optional, since they are only required by monotransitive and ditransitive verbs, as in the examples [2] and [3] above.
12.14 Some Untypical Sentence Patterns
The sentence patterns we looked at on the previous page represent typical or canonical patterns But you will often come across sentences which do not conform to these patterns. We will look at some of these here.

Extraposition
The Subject is sometimes postponed until the end of the sentence. Here are some examples:
In first place is Red Rum
Inside the house were two detectives
More important is the question of compensation
Here, the typical declarative order has been disrupted for stylistic effect. In these examples, the Subject comes after the verb, and is said to be EXTRAPOSED. Compare them with the more usual pattern:
In first place is Red Rum ~Red Rum is in first place
Inside the house were two detectives ~Two detectives were inside the house
More important is the question of compensation ~The question of compensation is more important
The Subject is also extraposed when the sentence is introduced by anticipatory it:
It is a good idea to book early
It is not surprising that he failed his exams
In the more typical pattern, these constructions may sound stylistically awkward:
To book early is a good idea
That he failed his exams is not surprising
Extraposition is not always just a matter of style. In the following examples, it is obligatory:
It seems that he'll be late again ~*That he'll be late again seems
It turned out that his secretary had stolen the money ~*That his secretary had stolen the money turned out
Direct Objects, too, can be extraposed. Recall that their typical position is after the verb (Pattern 2). However, when anticipatory it is used, the Direct Object is extraposed:
He made it very clear that he would not be coming back
Again, the canonical pattern is stylistically very awkward:
*He made that he would not be coming back very clear

Cleft Sentences
A declarative sentence, such as David studied English at Oxford can be reformulated as:
It was David who studied English at Oxford
This is called a CLEFT SENTENCE because the original sentence has been divided (or "cleft") into two clauses: It was David and who studied English at Oxford. Cleft sentences focus on one constituent of the original sentence, placing it after it was (or it is). Here we have focussed on the Subject David, but we could also focus on the Direct Object English:
It was English that David studied at Oxford
or on the Adjunct at Oxford
It was at Oxford that David studied English
Cleft constructions, then, exhibit the pattern:
It + be + focus + clause
13 Functions and Phrases
The syntactic functions which we looked at in the last section -- Subject, Object, Predicate, Adjunct, etc -- are all functions within sentences or clauses. We saw, for instance, that most sentences can be divided into two main functional constituents, the Subject and the Predicate:

Subject Predicate
[1] The lion Roared
[2] He writes well
[3] She enjoys going to the cinema
[4] The girl in the blue dress arrived late

Within the Predicate, too, constituents perform various functions -- in [3], for example, going to the cinema performs the function of Direct Object, while in [4], late performs the function of Adjunct. In each of these cases, we are referring to the roles which these constituents perform in the sentence or clause.
We can also assign functions to the constituents of a phrase. Recall that we have said that all phrases have the following generalised structure:
(pre-Head string) --- Head --- (post-Head string)
where the parentheses denote optional elements.
In this section, we will consider the functions of these parts of a phrase -- what roles do they perform in the phrase as a whole?
We will begin by looking at functions within verb phrases.
13.1 Complements
Consider the bracketed verb phrase in the following sentence:
David [VP plays the piano]
In formal terms, we can analyse this VP using the familiar three-part structure:

pre-Head string Head post-Head string
-- plays the piano

Let us now consider the functions of each of these three parts.
Actually, we already know the function of one of the parts -- the word plays functions as the Head of this VP. The term "Head" is a functional label, indicated by the capital (upper case) letter. Remember that we also capitalize the other functions -- Subject, Object, Predicate, etc.
Turning now to the post-Head string the piano, we can see that it completes the meaning of the Head plays. In functional terms, we refer to this string as the COMPLEMENT of the Head. Here are some more examples of Complements in verb phrases:

pre-Head string Head Complement
never needs money
-- eat vegetables
not say what he is doing

In each case, the Complement completes the meaning of the Head, so there is a strong syntactic link between these two strings.
At this point you may be wondering why we do not simply say that these post-Head strings are Direct Objects. Why do we need the further term Complement?
The string which completes the meaning of the Head is not always a Direct Object. Consider the following:
She [VP told me]
Here the post-Head string (the Complement) is an Indirect Object. With ditransitive verbs, two Objects appear:
We [VP gave James a present]
Here, the meaning of the Head gave is completed by two strings -- James and a present. Each string is a Complement of the Head gave.
Finally, consider verb phrases in which the Head is a form of the verb be:
David [VP is a musician]
Amy [VP is clever]
Our car [VP is in the carpark]
The post-Head strings here are neither Direct Objects nor Indirect Objects. The verb be is known as a COPULAR verb. It takes a special type of Complement which we will refer to generally as a COPULAR COMPLEMENT. There is a small number of other copular verbs. In the following examples, we have highlighted the Head, and italicised the Complement:
Our teacher [VP became angry]
Your sister [VP seems upset]
All the players [VP felt very tired] after the game
That [VP sounds great]
It is clear from this that we require the general term Complement to encompass all post-Head strings, regardless of their type. In verb phrases, a wide range of Complements can appear, but in all cases there is a strong syntactic link between the Complement and the Head. The Complement is that part of the VP which is required to complete the meaning of the Head.
13.2 Complements in other Phrase Types
Complements also occur in all of the other phrase types. We exemplify each type in the following table:

Phrase Type Head Typical Complements Examples
Noun Phrase (NP) noun PP


clause respect for human rights

the realisation that nothing has changed
Verb Phrase (VP) verb NP


clause


PP David plays the piano

They realised that nothing has changed

She looked at the moon
Adjective Phrase (AP) adjective clause

Adverb phrases are very limited in the Complements they can take. In fact, they generally occur without any Complement.
Noun phrases which take Complements generally have an abstract noun as their Head, and they often have a verbal counterpart:

the pursuit of happiness ~we pursue happiness
their belief in ghosts ~they believe in ghosts
the realisation that nothing has changed ~they realise that nothing has changed
13.3 Adjuncts in Phrases
The term "Complement" is not simply another word for the "post-Head string" -- post-Head strings are not always Complements. This is because the post-Head string is not always required to complete the meaning of the Head. Consider:
[NP My sister, who will be twenty next week,] has got a new job.
Here the relative clause who will be twenty next week is certainly a post-Head string, but it is not a Complement. Notice that it contributes additional but optional information about the Head sister. In this example, the post-Head string is an ADJUNCT. Like the other Adjuncts we looked at earlier, it contributes additional, optional information.
Adjuncts can occur in all the phrase types, and they may occur both before and after the Head. The following table shows examples of each type:

Phrase Type Head Typical Adjuncts Examples
Noun Phrase (NP) noun PP

AP
clause the books on the shelf

the old lady
cocoa, which is made from cacao beans
Verb Phrase (VP) verb AdvP

PP she rapidly lost interest

he stood on the patio
Adjective Phrase (AP) adjective AdvP it was terribly difficult
Prepositional Phrase (PP) preposition AdvP completely out of control
13.4 Complements and Adjuncts Compared
Complements differ from Adjuncts in two important respects:
1. Complements immediately follow the Head

In most phrases, the Complement must immediately follow the Head:
David [VP plays [Complement the piano] [Adjunct beautifully ]]
In contrast, the reverse order is not possible:
*David [VP plays [Adjunct beautifully] [Complement the piano]]
Similarly:
fond [Complement of biscuits] [Adjunct with coffee]
~*fond [Adjunct with coffee] [Complement of biscuits]
Complements, then, bear a much closer relationship to the Head than Adjuncts do.
2. Adjuncts are "stackable"
In theory at least, we can "stack" an indefinite number of Adjuncts, one after another, within a phrase. For example, consider the NP:
Adjunct Adjunct Adjunct Adjunct
the book on the shelf by Dickens with the red cover that you gave me...
In contrast with this, phrases are limited in the number of Complements that they can take. In fact, they usually have only one Complement. Ditransitive verb phrases are an exception to this. Recall that they take two Complements:
We [VP gave [Complement James] [Complement a present]]
13.5 Specifiers
Adjuncts can appear before the Head of a phrase, as well as after the Head. For example, in the following NP, the Adjunct sudden is part of what we have been calling the pre-Head string:
? Adjunct Head Complement
the sudden realisation that nothing has changed

In this section we will look at the function of the remaining part of the pre-Head string. In this example, what is the function of the in the phrase as a whole?
We refer to this part of the phrase as the SPECIFIER of the phrase. Again, Specifiers may occur in all the major phrase types, and we exemplify them in the following table:

Phrase Type Head Typical Specifiers Examples
Noun Phrase (NP) noun Determiners the vehicle
an objection
some people
Verb Phrase (VP) verb `negative' elements not arrive
never plays the piano
Adjective Phrase (AP) adjective AdvP quite remarkable
very fond of animals
Prepositional Phrase (PP) preposition AdvP just across the street

An important point about Specifiers is that they relate to the Head + Complement sequence, and not to the Head alone. For example, in the AP very fond of animals , the Specifier very relates to fond of animals, not just to fond:
Amy is very fond of animals
Q. Amy is very what?
A. *Fond
A. Fond of animals
In functional terms, then, the three-part structure of a phrase can be summarised as:
(Specifier) -- [Head -- (Complement)]
