Here's why:
* Adverbs modify verbs, adjectives, or other adverbs. They tell us *how*, *when*, *where*, or *to what extent* something happens.
* Nouns are words that name people, places, things, or ideas.
Example:
* The store is far away. (Far modifies the adjective "away")
* They drove far into the night. (Far modifies the verb "drove")
