What is Infinitive?

As an infinitive, we find a verb consisting of TO + V1 that functions as a noun, adjective, or adverb. For example – to go, to run, to love, to give, to sleep, to dance, to smoke, etc.

This kind of verb doesn’t change according to the subject or tense.

The following are three types of non-finite verbs in English:

  1. Gerunds
  2. Infinitives
  3. Participles


  • To walk daily improves your health.
  • To work is the only thing I want right now.
  • I just want to play.
  • One of my talents is to help people.
  • The person to meet is Max.
  • He bought the bike to sell it.

These first four examples use infinitives to function as nouns. The fifth one functions as an adjective, and the sixth one functions as an adverb.

Note: Negative infinitives are formed by using NOT before the word.

  • We decided not to play there.
  • He told me not to share it with anyone.
  • Not to play with him was the right decision.
  • Try not to cut the ball.

Functions of an Infinitives

Infinitive serves the following functions in sentences:

  2. The object of a verb
  3. The subject complement

Examples of infinitives as subjects

  • To see her daily is a privilege.
  • To work is my passion.
  • To have a supportive friend is a blessing.

Further, Infinitive phrases are made up of an infinitive and an object or a modifier. Other than the second example, all the subjects are infinitive phrases. In the second case, there is an infinitive, not an infinitive phrase.

Normally, infinitives are used as objects in a sentence. Generally, Gerunds or Gerund phrases are used as subjects of sentences

  • Seeing her daily is a privilege.
  • Working is my passion.
  • Having a supportive friend is a blessing.

Subject Complement: 

The subject complement is a word or group of words that renames or describes the subject. Generally speaking, a noun renames the subject, whereas an adjective modifies it.

3. Infinitive as Adverbs

An infinitive or an infinitive phrase can also work as an adverb. As an adverb, it helps to explain a verb. Look at the following example:

  • I came here to help you.

The infinitive phrase “to help you” modifies the verb ‘came’ and tells us the reason why it happened. Why did I come here? I came here in order to help you.

  • Max is working hard to earn more.
  • He called me last night to ask for a favor.
  • They have booked a car to go on the trip.
  • Whenever he gets angry, he does meditation to control his anger.

As an adverb, in simple words, infinitives tell us the purpose or the reason for the action. 


As, It is important to note that an infinitive or an infinitive phrase can also modify an adjective. Therefore, it functions as an adverb. In a sentence, it modifies the adjective as follows:

Structure: Subject + linking verb + adjective + infinitive/infinitive phrase

  • It is necessary to sleep properly.
    (modifying the adjective properly)
  • I am pleased to work with you.
    (telling us the reason of the adjective)
  • It was awesome to be on the top.
    (telling us the reason of the adjective)
  •  Everyone is sad to hear about your resignation.
    (telling us the reason of the adjective)
  • Emma was shocked to clear the interview.
    (telling us the reason of the adjective)

Bare infinitives in English

I just figured out what infinitives are. Now, where does this bare infinitive mean? You guys must be thinking that. Well, it is not something to be bothered about. Let me explain it to you.

A bare infinitive, also known as a zero infinitive, is an infinitive that does not have the particle TO in it. 

Further, We use bare infinitives after certain verbs: make, let, see, hear, watch, help, etc.


  • I made her take the test.
    (Here, take is the bare infinitive, and take the test is the bare infinitive)
  • My father does not let me play.
  • Did anyone watch him play the match?
  • She did not hear us talk about the media.
  • I helped you win the match.


These verbs are followed by an object first. Infinitives come after the objects of these verbs.

Bare infinitives are also used after had better, better, and would rather.

  • You had better start working alone.
  • She would rather kill herself.
  • We better do something about the safety.

Similarly, bare infinitives are also used after modal auxiliary verbs: can, could, may, might, should, would, will, shall, must, etc.
