What's "Infinitive" in English Grammar

 

Infinitive In English Grammar:-

In English grammar, an infinitive is the base form of a verb that is typically preceded by the word "to." It is often used as a noun, adjective, or adverb to indicate purpose or intent. 

For example: In the sentence; 

"I like to swim," the infinitive is "to swim." 

The infinitive can also be used without the "to" in certain constructions, such as in "I must swim."

It is a non-finite form of verb, means it does not have a subject and it can not indicate the time when the action happened.

It can also be used without any preposition after an object form. For example:

"He made the people work"

It can also indicate a hypothetical situation and some other purpose, like "It's good to swim"
