Adjectives are words that modify, or add to and clarify the meaning of, nouns and pronouns. Adjectives describe people, places, or things by telling what kind, how many, or which one. An adjective that appears after a linking verb and describes a noun in the subject is a predicate adjective. Sometimes words that we think of as nouns are used as adjectives.
