In grammar, an adjective is a word whose main syntactic role is to modify a noun or pronoun, giving more information about the noun or pronoun's referent. Collectively, adjectives form one of the traditional English eight parts of speech, though linguists today distinguish adjectives from words such as determiners that also used to be considered adjectives.
Not all languages have adjectives, but most, including English, do. (English adjectives include big, old, and tired, among many others.) Those that do not, typically use words of another part of speech, often verbs, to serve the same semantic function; Even in languages that do have adjectives, one language's adjective might not be another's;
In most languages with adjectives, they form an open class of words; that is, it is relatively common for new adjectives to be formed via such processes as derivation
In many languages, attributive adjectives usually occur in a specific order. Generally, the adjective order in English is;
article or pronouns used as adjectives
intensifier quality, size ,age, color ,participle, proper adjective ,noun used as adjectives ,headnoun
