An adjective phrase is a phrasal syntactic category in which the syntactic head, that is the most important element, is the adjective. There are different kinds of adjectives in TİD [Lexicon - 3.4.]. An adjective in TİD can denote quality, size, shape, color, origin, value, dimension, physical property, speed, human propensity and age. The adjectives can occur as adjuncts of noun phrases (NP) in the prenominal and postnominal positions [Syntax – 4] and as predicates. This chapter focuses on the internal structure of adjective phrases and provides examples and descriptions of intensifiers and other modifiers of adjectives, adjectives that function as predicates and take arguments, and adjuncts of adjectives.
