Why is reasonable an adjective?

"Reasonable" is an adjective because it describes a noun.

Here's why:

* It modifies nouns: It tells us something about the quality of a noun.

* "She made a reasonable request." (Describes the request)

* "He gave a reasonable explanation." (Describes the explanation)

* It answers the question "what kind?" or "which one?":

* "What kind of request did she make?" - "A reasonable one."

* "Which explanation did he give?" - "The reasonable one."

Here's how it contrasts with other word types:

* Verb: A verb expresses an action or state of being. (e.g., "She reasoned with him.")

* Adverb: An adverb modifies a verb, adjective, or another adverb. (e.g., "She reasonably asked him to leave.")

* Noun: A noun names a person, place, thing, or idea. (e.g., "Reason is important.")
