I knew that thanks for comment :)

A gerund is a noun made from a verb. To make a gerund, you add "-ing" to the verb.

For example:

In the sentence "I swim every day", the word "swim" is a verb.

In the sentence "I like swimming", the word "swimming" is a noun.

Therefore, "swimming" is a gerund.

An infinitive is the basic form of the verb + "to".

Examples: to buy, to fish, to run, to watch, to tell, and so forth.
