Here's why:
* Adverbs modify verbs, adjectives, or other adverbs. They tell us how, when, where, or to what extent something happens.
* Adjectives describe nouns or pronouns. They tell us what kind, which one, or how many.
Examples:
* Adverb: "She spoke confidently." (Modifies the verb "spoke")
* Adjective: "He has a polished presentation style." (Describes the noun "presentation style")
Note: The word "polished" can be used as part of a verb phrase, such as "polished the shoes." In this case, "polished" acts as the past participle of the verb "to polish."
