Finite and Non-finite verbs


 

FINITE AND NON-FINITE VERBS

 

FINITE VERBS:

A finite verb is controlled by the number of the subject. If the subject is singular, the verb is singular. If the subject is plural, the verb is plural.

Eg: The girl runs slowly. (Subject is singular)

    The girls run slowly. (Subject is plural)

 

A finite verb is controlled by the person.

Eg: I visit my grandparents at least once a month. (I – First Person)

    She visits her grandparents at least once a month. (She – Third Person)

 

A finite verb is controlled by the tense. It can be in the past, present or future tense.

Eg: Madhan studiesFrench. (Present Tense)

    Mani will study Spanish. (Future Tense)

 

NON-FINITE VERBS:

A non-finite verb is not controlled by the number, person and tense of the subject In other words, it is a verb form, which does not function as a verb.

Eg: I enjoy shopping for clothes and shoes.

    You enjoy shopping for clothes and shoes.

They enjoy shopping for clothes and shoes.

 (The verb shopping remains unchanged whatever be the person, number and tense of the subject.)

 

Non-finite verbs are of three kinds:

They are,

1 Infinitives,

2 Gerunds and

3 Participles.

 

Examples:

She can’t go out . (Zero Infinitive)

I want to go to the cinema. (To-Infinitive)

I like going to the cinema. (Gerund)

I wish I had gone to university. (Past Participle)

I’m going to a concert tonight. (Present Participle)

 

Let us learn the three forms of non-finite verbs in detail:

1 INFINITIVES:

The infinitive is often called as “TO verb”.

Infinitive can function ass a subject and object

Eg: To swim is a good excersise -      as a subject

    I like to swim                                   -           as an object

 

When ‘to’ is added to a verb, it is an infinitive. It is used as a subject or an object or a complement in a sentence.

I) Infinitive used as a subject:

a. To err is human.

b. To forgive is divine.

 

II) Infinitive used as an object:

a. I like to swim.

b. I want to learn English.

 

III) Infinitive used as a complement:

a. My aim is to join the army.

b. His ambition is to serve mankind.

 

Infinitives may be used without “to” and we call such infinitives a plain infinitives or a bare infinitives

Eg: She made me do my project

 

We use plain/bare infinitives with these models such as, Shall, may, will, might, do, could, did, must, would, let, make, dare, need, see

 

The infinitives may function as subject, direct object, subject complement, adjective or adverb in a sentence. Although an infinitive is easy to locate because of the “To + Verb form” deciding what function it has in a sentence depends on the meaning

Eg: To wait seemed foolish when decisive action was required(subject)

    Everyone wanted to go(direct object)

    His ambition is to fly(subject complement)

    He lacked the strength to resist(adjective)

    We must study to learn(adverb)

 

The following list of verbs must be followed by an infinitive; not any other kinds of non-finite verbs:

  • Seem, Offer, Hesitate, Demand, Wish, Refuse, Need, Forget, Decide, Want, Pretend, Learn, Fail, Claim, Tend, Prepare, Intend, Expect, Attempt, Strive, Plan, Hope, Desire, Agree

 

2 GERUNDS:

A gerund is an action word that ends in – “ING” in other words Gerund is a verbal noun, a participle or an adjective.

It is used as a subject or an object or a complement and also with a preposition.

3 PARTICIPLES:

Participles may function as adjectives, describing or modifying nouns.
