Adjectives are words that 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 different forms of adjectives depending on their degree: positive, comparative, and superlative. Comparative is used to compare two items while superlative compares more than two items. Some adjectives require "more" for comparative and "most" for superlative forms. Adjectives follow a typical order when used together before a noun.
