Adjectives modify nouns and pronouns by describing, identifying, or quantifying them. Adjectives typically appear immediately before the noun they modify or after linking verbs. There are three degrees of adjectives: positive, comparative, and superlative. The positive form is the base adjective. The comparative form is used to compare two items and uses "-er" or "more." The superlative form compares more than two items and uses "-est" or "most."
