ADJECTIVE

In grammar, an adjective is a word used to denote some quality in the noun or substantive to which it is accessory. The adjective is indeclinable in English (but has degrees of comparison), and generally precedes the noun, while in most other European languages it follows the inflections of the substantive, and is more commonly placed after it, though in German it precedes it, as in English.
