An adjectival phrase functions as a modifier of the noun (SYNTAX 4.5). The head of this syntactic construction is an adjective (LEXICON 3.4). In this chapter, we show that the adjectival head can be modified both manually and non-manually (SYNTAX 5.1), it can select arguments of different types (SYNTAX 5.2), and it can be modified by adjuncts (SYNTAX 5.3).
