Here's why:
* Adverbs modify verbs, adjectives, or other adverbs. They tell us how, when, where, or to what extent something happens.
* Nouns name people, places, things, or ideas.
* Pronouns replace nouns to avoid repetition.
Examples of "ever" as an adverb:
* "Have you ever been to Paris?" (modifies the verb "been")
* "This is the ever-lasting flame." (modifies the adjective "lasting")
* "She sang ever so sweetly." (modifies the adverb "so")
