Here's why:
* Adverbs modify verbs, adjectives, or other adverbs. They tell us how, when, where, or to what extent something is done.
* Verbs express actions or states of being.
Example:
* Quite a lot of people came to the party. (Here, "quite" modifies the noun phrase "a lot of people".)
* I quite like that song. (Here, "quite" modifies the verb "like".)
