Word, Phrase, Clause, Sentence
1. Word
A word is a string of letters
carrying one or more meanings. The article 'a' is the only word in English
which consists of one letter only.
Watch, Run. Beautiful, Happily,
The, An, John, City are just a few examples of words.
Phonetic Structure of a word
Phonetically, a word may consist of one or more syllables.
A syllable is a word or a part of a
word which may consist of a single phoneme (sound use in the concerned
language) or more.
A syllable is only a phonetic unit
and not a lexical unit as it need not carry any meaning.
If it consists of one phoneme only,
that phoneme must be a vowel. The article 'a' is perhaps the only word which
consists one mono-phonemic syllable.
The number of phonemes in a word
can be anything between one and eight. One of the phonemes in a syllable must
be a vowel. There is only one vowel in a syllable. The other phonemes, if they
are there, are consonants.
The vowel is the mandatory element
in a word. There can be no syllable without a vowel. And we cannot have more
than one vowel in one syllable. It is also the nucleus (the central element).
The consonants are optional
elements. They may or may not be there. They are also marginal elements and
occur before the vowel (two), after the vowel (an) or both sides of
it (run). The maximum permissible number of consonants before the vowel is
three and the maximum number permissible after the vowel is four. However,
syllables having eight phonemes are rare.
We must remember here that we are
talking of phonemes (sounds of the language), not of the letters of the
alphabet. It is an important fact to remember because, sometimes, a phoneme,
whether vowel or a consonant, is spelt with more letters than one.
There are three consonants in
English which may sometimes function as vowels in a syllable. That is why they
are called syllabic consonants. The are /m/ (rhythm), /n/ (button), and /l/
(bottle)
Morphological Structure of a word.
A morpheme is a lexical unit. It always carries some meaning. It may
be a word or a part of a word.
A word may be mono-morphemic or
poly-morphemic. It is mono-morphemic if it cannot be divided further into
meaningful parts. Such a word is called the base or the root morpheme.
The morphemes that are affixed
before the root to derive lager words or inflected forms of words are called
affixes. The affixes may be prefixes (be--- in befriend and un---- in unhappy).
Those which are affixed to the end of the root are called suffixes
(------ness in happinesss and ------ful in beautiful).
Those which are inserted in the
middle of the root are called infixes (-----s----- in fathers in-law and
mothers-in-law).
All the affixes cited
above are derivative affixes. We get a word belonging to a different part of
speech when they are added to the root.
There is another
category of affixes known as inflectional affixes. When they are added to
a root, we get a different form of the same word which belongs to the
same part of speech. ---s in brothers, ----ess in poetess, ---ed in reported,
and ----er in greater are some examples of inflectional affixes.
Phonetically, a word may consist of one or more syllables.

A morpheme is a lexical unit. It always carries some meaning. It may be a word or a part of a word.
Parts of Speech
So far as English is concerned,
words can be divided into the following ten categories:
I. Nouns
II. Verbs III. Adjectives
IV. Adverbs V. Pronouns
VI. Determiners: a)
Articles b) Demonstratives c) Cardinal
Numerals d) Ordinal Numerals
e) Indefinite Numerals f) Quantifiers
VII. Conjunctions
VIII. Prepositions IX. Interjections
I. Nouns
A noun is the name of a person, place,
group, thing or an abstract concept. Shakespeare, London, class, book,
honesty are some examples of nouns
Nouns can be classified into the
following categories:
1. Proper Nouns: A
proper noun is the name of a particular person, place or thing and cannot be
applied to another specimen of the same type. Keats, Birmingham, India etc. are
proper nouns. We may include her the one word titles or captions given to
pieces of art such as books, paintings, sculptures etc.
2. Common Nouns: Common
nouns are names given to persons or things which can be applied to any specimen
of the same type. Horse, book, city, man, animal, bird, worm etc. are some
examples of common nouns.
3. Collective Nouns: Collective
nouns are nouns used for groups of things, men, animals etc. Class, Army, herd,
flock, parliament etc. are some examples of collective nouns.
4. Material Nouns: Material
nouns are names given to different types of matter that things are made of.
Soil, iron, wheat, flour, concrete, cement etc. are some examples of material
nouns.
5. Abstract Nouns: Abstract
nouns are names of concepts that exist only in the mind and do not
have any physical existence. Honesty, loyalty, bravery, courage, fear,
cowardice, nationality etc. are some examples of abstract nouns.
II. Verbs
Verbs are words that denote the
happening of some act or activity or event or a state of being.
Be, lie, run, walk, talk, return,
support, raid, invade, protect, defend etc. are examples of verbs.
Types of Verbs
Verbs can be classified in the
following way.
A. Intensive and Extensive
i. Intensive Verbs
Verbs which can be followed only by
subject complements are known as INTENSIVE verbs. Their function is just to
connect the subject with the subject complement. They are also known as
copulas.
The verb BE is the most commonly
used intensive verb (copula). There are others which mean prove to be, become,
appear or change from one state to another. Turn out to be, prove to be, seem,
appear, sound, look, feel, taste, smell, get, become are some frequently used
intensive verbs. Intensive verbs do not denote an action. They denote a fact or
a state or a change of state.
You are very
lucky.
He became famous
overnight.
The man known for his loyalty to
the king turned out (proved) to be a traitor.
The courtier turned traitor
just for a bit of money.
The ugly child grew up into a
handsome young man.
Sugar tastes sweet.
Flowers smell sweet.
The song sounded extremely
melodious.
He got frustrated
as a result of repeated failures.
Velvet feels soft to
touch.
The light changed to red
before we could reach the crossing.
It has to be noted that some of
these verbs such as change, turn, feel, taste etc. are also sometimes used as
extensive verbs. When they are used in the extensive sense, they are not
followed by a subject complement.
Just one goal changed the
colour of the game.
The doctor felt the
pulse of the patient.
He tasted the
pudding before serving it to the guests.
The child smelt the
flower.
ii. Extensive Verbs
Verbs which are not followed by a
subject complement are known as EXTENSIVE verbs. These verbs normally denote an
action.
Extensive verbs are divided into
two categories: INTRANSITIVE and TRANSITIVE.
A. Intransitive Verbs
Intransitive verbs are verbs which
do not require an object to follow them because the action they denote does not
affect anything or any person or create anything new.
Children are playing in
the field.
The labourers are working in
the field.
The baby is crying.
B. Transitive Verbs
Transitive verbs are verbs that
must be followed by at least one object. But they may sometimes be followed by
two objects.
On the basis of the mandatory elements
they demand after them, transitive verbs can be divided into three categories:
MONO-TRANSITIVE, DITRANSITIVE and COMPLEX TRANSITIVE.
I. Mono-transitive Verbs
Mono-transitive verbs are verbs
that require one object to follow them. The object that follows them is known
as the DIRECT object.
He has changed his
dress.
I am reading a
novel these days.
The painter has painted a
beautiful portrait.
We are planning our
course of action.
The king punished all
the traitors.
We play football in
the evening.
The words in bold type are verbs
and those in italics are objects. As you see, all these verbs are followed by
one object only
II. Di-transitive Verbs
Di-transitive verbs are verbs which
have to be followed by two objects. One of them is called the direct object and
the other the indirect object. Normally, the indirect object precedes the
indirect object. But the order may be changed and the indirect object may be
moved behind the direct object. When this is done, a preposition is inserted
before it. The prepositions used for this purpose are TO and FOR.
My father bought me a
new shirt on my birthday.
Grandmother told us an
interesting story last night.
My friends gave me a
costly gift on my marriage anniversary.
The company has offered me a
lucrative job.
The sentences may be rewritten
after changing the order of the objects as follows:
My bought a new shirt for me on
my birthday.
Grandmother told an
interesting story to us last night.
My friends gave a costly
gift to me on my marriage anniversary.
The company has offered a
lucrative job to me.
The objects in bold type in the
above sentences are the indirect objects the ones in italics are the direct
objects.
It may be noted here that the
indirect object is generally a person and the recipient of the direct object.
The direct object is a non-person (a thing) which is received by the indirect
object.
III. Complex Transitive Verbs
Complex transitive verbs are verbs
that have to be followed by a direct object which then is followed by an object
complement.
1. Marriage has made him very
happy.
2. We elected him our
leader.
3. The teacher called me a
hero.
4. Circumstances have made him what
he is.
5. Hard struggle against heavy odds
makes us brave.
6. They call this metal iron in
English.
The expressions in bold type are
direct objects and those in italics are object complements.
As you can see, the object
complement can be a noun, a noun phrase, a noun clause, an adjective or an
adjective phrase. In sentence 1, it is an adjective phrase and in sentence 5,
it is an adjective. In sentence 6, it is a noun, in sentences 2 and 3, it is a
noun phrase and in sentence 4, it is a noun clause.

Stative and Dynamic Verbs
Another way of classifying verbs is
on the basis of whether they can be used progressively or not.
Verbs which cannot be used in a
progressive (continuous) aspect of a tense are called stative verbs. The verbs
in the following sentences are stative:
i. The
tea is hot.
ii. A
stone feels hard to touch.
iii.
Sugar tastes sweet.
iv.
Flowers smell sweet.
It is clear that we cannot say i.
The tea is being hot. ii. A stone is feeling hard iii.
Sugar is tasting sweet iv. Flowers are smelling sweet.
We have to be on our guard here
because the same verb may be stative in one usage and dynamic in another usage.
Look at the following sentences. They contain the same verbs but the verbs have
been used as dynamic verbs.
i. The
man is being brave (trying to show that he is brave).
ii. The
doctor is feeling the pulse of the patient.
iii. She
is tasting the tea.
iv. He
is smelling a flower.
III. Adjectives
Adjectives are words that qualify a noun by referring to some quality or property that it possesses. Brave, big, small, honest, beautiful,
regular, continuous, hard, soft etc. are examples of adjectives.
Adjectives can be used as
pre-modifiers or complements.
A brave man does
not fear death.
My friend is brave.
A few may even be used as
post-modifiers of nouns as general in attorney general.
IV. Adverbs
Adverbs are words that are
used to modify or qualify verbs.
i. He
faced the problem bravely.
ii. I
attend classes regularly.
iii. You
speak very loudly.
iv. He
ran very fast to win the race.
In iii. and iv. , the adverb in bold type, which is the head of the verb phrase, has itself been modified by another adverb.
In iii. and iv. , the adverb in bold type, which is the head of the verb phrase, has itself been modified by another adverb.
V. Pronouns
Pronouns are words that can replace
nouns after their first appearance. They refer to the entities referred to by
the antecedent nouns. The normal practice is that a pronoun is used to replace
a noun after the noun has occurred. In some rare cases, the noun may occur
after the pronoun.
Pronouns can be classified into the
following types:
i. Personal pronouns - Personal
pronouns are pronouns that are used to refer to persons. I, you, he,
she, they, my, your, his, her, their and myself are some examples of
personal pronouns.
Personal pronouns have different
forms (cases) which are used in different positions.

----------------------------------------------------------------------------------------------------------------
(M) =
Masculine (F) = Feminine
----------------------------------------------------------------------------------------------------------------
When the pronoun is the subject in
the sentence, the subjective case is used. When it is the object, the objective
case is used. The possessive adjectival is used before a noun to show
possession. The nominal possessive is used like a noun and the noun does not
follow it. The reflexive case is used when the subject itself is the object
also.
The reflexive case is also used for
emphasis as in the following sentences:
i. Personal pronouns - Personal
pronouns are pronouns that are used to refer to persons. I, you, he,
she, they, my, your, his, her, their and myself are some examples of
personal pronouns.
3rd Person
1. I delivered the letter to the boss
myself. Or I myself delivered the letter to the boss. (Did not entrust the job
to anybody else
2. I delivered the letter to the boss
himself. (Not to anybody else)
When the reflexive case
is preceded by the preposition BY, it means alone i.e. without anybody else’s
help or not accompanied by anybody.
1. I did all the work by myself.
2. The old man and his wife are sitting by themselves.
To further emphasise the fact, the word all may be inserted
before ‘by’.
ii.
Demonstrative Pronouns
THIS and THAT are singular demonstrative pronouns used
respectively to demonstrate the referents that are near and at a distance.
THESE and THOSE are their plural counterparts.
iii.
Interrogative Pronouns
These are pronouns used to ask questions. WHO, WHOM, WHOSE
are personal interrogative pronouns and WHAT and WHICH are non- personal. Of
the former, WHO is subjective, WHOM is objective and WHOSE is possessive.
iv.
Indefinite Pronouns
These are pronouns used to refer to things or persons not
yet identified. All, some, any, several, many, few, a few, much, little, a
little, anybody, somebody, anyone, someone, no one, none, anything, nothing, each,
both every one, either, neither, everything are some commonly used indefinite
pronouns. To this list, we may also add whatever, whoever, whosoever,
whatsoever and whomsoever.
v.
Relative Pronouns
Relative pronouns are pronouns used as conjunctions to link
a relative (adjective) clause to the antecedent noun.
WHO, WHOM and WHOSE are relative pronouns used for persons.
WHICH and OF WHICH are used for non-persons.
vi.
Reciprocal Pronouns
Reciprocal pronouns are used to denote the reciprocation of
an action or gesture by two or more people or things. When two things or
persons respond to in a manner similar to the one in which they have been
treated, reciprocal pronouns are used to refer to their mutual responses.
Each other and one another are two reciprocal pronouns used
in English. Each other is used when only two participants involved and one
another is used when there are more than two.
VI. Articles
i. Articles – The words a, an, and the are known as articles in English. A and an are indefinite articles used before the singular forms of countable nouns when their referent is unidentified.
The article a is used before a singular noun beginning with a consonant sound and an before a singular noun beginning with a vowel sound.
The is the definite article which can be used before both
countable (singular as well as plural) and uncountable nouns when their referent
is identified.
VII. Conjunctions
Conjunctions
are linking words. They are used to link words, phrases or clauses. There are
two types of conjunctions:
1. Coordinating conjunctions - These are conjunctions used to link words or
phrases in a sentence of the same class in a sentence or a clause or the
coordinate clauses of a compound sentence.
They
can also conjoin the clauses of the same type in complex sentences.
Some examples of coordinating conjunctions
are: And, Or, But, Yet, So, Nor, As well as etc.
We also have some pairs of coordinating
conjunctions: Neither --- nor, Either --- or, Both --- and, Not only --- but (also) etc.
Coordinating conjunctions can conjoin
similar clauses of a complex sentence also i.e. to conjoin a main clause with a
main clause or s subordinate clause with a subordinate clause.
1. He engaged a tutor and burnt the
midnight oil because he wanted to top the class.
2. Corona can be controlled more
effectively if we seal the affected areas but allow normal economic activity to
go on in other areas.
2. Subordinating conjunctions:
Subordinating conjunctions are conjunctions used to conjoin the subordinate
clauses to the principle (main) clauses in complex sentences.
There is a long list of subordinating
conjunctions and we have to make our choice keeping in mind the type of the
subordinate clause.

Adverb Clauses – The choice depends on the type of the adverb clause.
A Preference clauses - Rather than, Sooner than
An interjection is an exclamatory word expressing a sudden burst of emotion or strong feeling.
2. Phrase
A phrase is a small
meaningful group of words standing together as a conceptual unit that can be
used to realise an element of a sentence or to pre-modify or post-modify a
noun. We come across the following types of phrases in English
i. Noun Phrase – A noun phrase is a phrase having a
noun as its head. The head noun may be pre-modified by an adjective, a noun, a
present participle, a past participle or post-modified by a prepositional
phrase, a present participle phrase, a past participle phrase, or an adjective
clause. A very nice man, an on the spot inquiry, a factory worker, a patriot to
the core, the boy with a red turban, the man standing in the middle of the
crowd, the messenger who brought the tidings are some examples of noun phrases.
ii. Verb Phrase – A verb phrase is a phrase having a
verb as its head. The head verb in the phrase may be preceded by one or more
auxiliaries depending on the tense, the aspect and the voice. The auxiliaries
do not exceed three. Some examples of verb phrases are:
is reading, was thinking,
will be coming, is being done, will have done, might have been completed,
should have been amended.
iii. Adjective Phrase – An adjective phrase is a phrase
headed by an adjective. The adjective head may be pre-modified by one or more
adverbs or post –modified by a prepositional phrase.
Thoroughly honest, stupid
to an extreme, wise as an angel are some examples of adjective phrases.
iv. Adverb Phrase – An adverb phrase is a phrase having an adverb as its head. The adverb
may be pre-modified by another adverb or by an adverb clause of manner or
comparison.
He did the
job well.
He did the job
well enough.
He did the job
extremely well.
He did the job
as well as I expected.
He did the job
better than I expected.
v.
Prepositional Phase – A
prepositional phrase has a preposition which is placed initially. The
preposition is then followed by a noun or noun phrase. It is used to modify a
noun or an adjective or an adverb or to realise the adverbial element in a
clause.
People inside the house did not answer the traveller’s call. (Noun
modifier)
It is not easy
to drive in the dark. (Adverbial)
This man is generous to a fault. (Adjective modifier)
The child ran around in circles. (Adverb modifier)
He performed best of all. (Adverb modifier)
3.
Clause
A clause is a string of words of words or phrases which
contains all the essential elements of a sentence but, instead of being an
independent sentence carrying a complete meaning, is a part of a larger
sentence in which it plays the role of one of the elements.
Sentences having more clauses than one are divided into two
types: compound sentences and complex sentences.
A.
Compound Sentences – The
following sentences contain two clauses each joined together by a coordinating conjunction. Both the clauses are
independent and enjoy equal status.
Just remove the conjunction and you get two complete independent sentences.
I asked
him a question but he did not give any answer.
I asked him for help and he obliged me.
You must work hard or you will fail.
He might have worked hard or he might have
cheated in the examination.
In the following sentences, some word/s
has/have been ellipted or substituted in one of the clauses.
It was
not he who helped me but his brother. (Ellipted words- who helped me)
I
requested him to help me and he did. (Did substituted for helped me)
B.
Complex Sentences – In
a complex sentence, the conjoined clauses are neither independent nor of equal
status. One of them is the principle clause and the other is the subordinate
clause. There are three types of subordinate clauses.
i.
Noun clauses – They can occur as the subject, the
direct object or the complement (both subject and object) in a sentence.
What he said was not true. (Subject)
He
said that he has passed the test. (Direct object)
He
told me that he would be visiting Paris
next year. (Direct
object)
We
become what destiny makes us. (Subject complement)
Hard
work has made him what he wanted to
become. (Object
complement)
ii.
Adjective
(Relative clauses - They
can be used to post-modify nouns.
The
team that wins the competition gets the gold medal.
We
must work hard to achieve the goal we set
ourselves.
iii. Adverb
clauses – Adverb clauses
are clauses that qualify the verb. On the basis of the information contained in
them, they are classified as follows:
a. Adverb clause of time
I was
watching T.V. when my friend came to
visit me.
b. Adverb clause of place
He put
the book where I told him to.
c. Adverb clause of manner
The
student delivered the dialogue as the
teacher had directed him to.
d. Adverb clause of reason
He
succeeded in life because he worked very
hard.
e. Adverb clause of purpose
The
athlete is practising hard so that he may
win the gold medal.
f. Adverb clause of result
He ran
so fast that he won the race easily.
g. Adverb clause of condition
You
will definitely achieve your goal if you
show enough determination.
h. Adverb clause of comparison
The
picture my friend painted was better than
the one that I had painted.
i. Adverb clause of contrast or concession -
Although he is poor, he is honest.
j.
Adverb
clause of proportion
The
higher you go, the cooler it is.
His performance got worse as he got disheartened.
h. Adverb clause of preference
Rather than take a train, I would like to go by air.
Modern grammarians like Randolph Quirk and Sydney Greenbaum consider infinitive, present participle and past participle phrases also as clauses. They call them non-finite clauses. Non-finite clauses cannot show tense and mood. They have to be inferred from the context or the finite clause accompanying them. But they can show aspect and voice. However, they cannot show the full range of aspects. Only the simple (indefinite) and perfect aspect can be expressed in them.
4.
Sentence --
A sentence is
a string of words or phrases arranged in accordance with the grammatical
requirements of a language so that it carries a complete sensible meaning. It
may be simple (consisting of one clause only), compound (consisting of two or
more clauses joined together by a coordinating conjunction such as and, or, but
etc.), or complex (in which clauses are joined together by subordinating
conjunctions of different types).
1. The boys are playing in the playground.
(Simple)
2. Be silent or leave the room.
(Compound)
3. He tried hard but could not open
the lock. (Compound with subject ellipted)
4. I know where he lives. (Complex)
5. He told me that he had acted in
more than twenty films. (Complex)
6. The bird which has built this
nest is known as the weaver bird. (Complex)
7. We shall start for the fair as
soon as my friend arrives. (Complex)
