Is clearly an adverb a verb or adjective?

"Clearly" is an adverb. It modifies verbs, adjectives, or other adverbs.

Here's why it's not a verb or adjective:

* Verb: Verbs describe actions or states of being. "Clearly" doesn't describe an action or state of being.

* Adjective: Adjectives describe nouns. "Clearly" doesn't describe a noun.

Examples:

* Modifying a verb: She clearly understood the instructions.

* Modifying an adjective: It was a clearly written report.

* Modifying another adverb: The car drove very clearly through the intersection.
