Adjectives describe nouns (words that name people, places, or things) and pronouns (words that replace nouns). They add information about what kind, which one, or how many.

Adverbs describe verbs (words that tell what happens in a sentence), adjectives, or other adverbs. They add information about how, how much, when, where, why, or to what degree. Adverbs often end with -ly.

Adjectives usually come before the words they modify; adverbs come either before or after. You can also use more than one adjective or adverb to modify a word.
