adjective

n. part of speech used to modify a noun (Grammar)

In grammar, an adjective is a word whose main syntactic role is to modify a noun or pronoun (called the adjective's subject), giving more information about what the noun or pronoun refers to. Collectively, adjectives form one of the traditional eight parts of speech, though linguists today distinguish adjectives from words such as determiners that used to be considered adjectives but that are now recognized to be different.
