What are adjectives?

An adjective is a word like kind, happy, smart and intelligent. An adjective typically modifies a noun and denotes a temporary or permanent quality associated with that noun. For example, a smart boy is a boy who is distinguished from other boys by being smart.

Not all adjectives are used to denote a quality associated with a noun. For example, the adjective mere in ‘a mere child’ does not denote a quality of the child.
