Here's a breakdown:
Adverbs:
* Describe verbs, adjectives, or other adverbs. They answer questions like "how?" "when?" "where?" "to what extent?"
* Examples: quickly, loudly, yesterday, here, very
Pronouns:
* Replace nouns. They refer to people, places, or things that have already been mentioned.
* Examples: he, she, it, they, we, you, I, this, that
Key differences:
* Function: Adverbs modify other words, while pronouns replace nouns.
* Types: Adverbs have many categories (time, place, manner, etc.), while pronouns have specific categories (personal, possessive, etc.).
* Examples: "The dog ran quickly." (quickly is an adverb modifying the verb "ran") vs. "He ran quickly." (He is a pronoun replacing the noun "dog")
Think of it this way: adverbs tell you how, when, or where something happens, while pronouns tell you who or what is involved.
