What is Infinitive?

Infinitive is one kind of Non-Finite Verbs in English which comes in an original form of verb. We have two types of Infinitive which Infinitive with to and Infinitive without to. Both of them use in different ways and here we are going to learn about how to use them.


Infinitive with to

The “to + V.infinitive” has functions as follows :

1. It can function as a noun and be a subject or an object of the sentences.

Example : To watch movies is my favorite hobby. Chompoo loves to watch movies with her husband.

2. It can function as Adjective.

Example : Gina has a lot of works to do today.

3. It can function as Adverb.

Example : Peter comes to buy a gift for his wife.


How to use “to + V.infinitive”

  • After the following verbs :attempt, afford, agree, appear, arrange, care, decide, deserve, determine, fail, forget, happen, hesitate, hope, hurry, intend, learn, manage, offer, plan, prepare, pretend, promise, prove, rail, refuse, seem, threaten

Example : Paul agrees to invest in this project. She refuses to come with him.

  • After the following verbs in the structure “Subject + Verb + Object + to + Infinitive”

advise, allow, cause, challenge, command, encourage, force, get, instruct, invite, lead, order, persuade, remind, teach, tell, urge, warn

Example: The teacher reminds the students to review the lessons. The General encourages his soldiers before the task.

  • After question words : what, where, when, why, who, how

Example : We don’t know where to leave our luggage. This TV channel will teach you how to cook easy menu.


Infinitive without to

How to use “Infinitive without to”:

  • After Modal Verbs – must, need, may, might, can, could, will, would, shall, and should

Example : You must wake up at 6 am. otherwise you will go to school late. Everything might be better. Katie could go to a club tonight.

  • After “had better” and “would rather”

Example : It is going to rain, you’d better bring an umbrealla. Sompob would rather drink coffee than tea.

  • After “let, make, have, help + object (someone)”

Example : Can you help me finish this job? Ploy has the hairdresser dry her hair. The movie was very funny. It made me laugh.

  • After Verb of perception – see, hear, feel + object

Example : He saw the lights turn on. Can you feel the house shake?

Now, you can see the different between “infinitive with to” and “infinitive without to”. We use them a lot in everyday english and of course, in TOEIC because it is a test in english communication. I suggest you not only try memorizing words which always used in infinitive forms but also try practicing these words in your everyday life. The more you use them, the more you can memorize them. Language skill is a thing that depends on how often you develop your skill. See you next issue.
