Adjective

In grammar, an adjective is a 'describing' word; the main syntactic role of which is to qualify a noun or noun phrase, giving more information about the object signified.
Adjectives are one of the traditional eight English parts of speech, though linguists today distinguish adjectives from words such as determiners that were formerly considered to be adjectives. In this paragraph, "traditional" is an adjective, and in the preceding paragraph, "main" and "more" are.
