Here's why:
* Verb: A verb describes an action, state, or occurrence.
* Noun: A noun names a person, place, thing, or idea.
Gerunds are formed by adding "-ing" to the base form of a verb. They act like nouns and can function as:
* Subject of a sentence: *Swimming* is my favorite activity.
* Object of a verb: I enjoy *reading*.
* Object of a preposition: I am good at *cooking*.
