An adjective is a word used to modify, or describe, a noun or pronoun. An adjective usually answers one of these questions: Which one? What kind of? How many?
Adjectives ordinarily modify nouns or pronouns. They usually precede the words they modify.
Occasionally they function as subject complements following linking verbs.
