What is an "infinitive"?

An Infinitive is the verb form that has “to” at the beginning.

For example,

to do

to sleep

to love

to create

It is the simplest verb form that you have to modify to fit into sentences.

Infinitives (positives and negatives)

• to + base form

• to play

• not to + base form

• not to play

Some examples:

• I need to eat something.

• It's important not to come late.

• I bought two tickets to go to the concert.

• I don´t know what to say. I don't love you anymore.

Examples:

• It's nice to meet you.

• It's important not to be late.

• I'm happy to accompany you.

Infinitives to indicate the purpose or intention of an action.

In this case TO has the same meaning as IN ORDER TO.
