Typology of Nominalisation of Adjectives in East Caucasian

Traditionally, functioning of major classes of lexical items is described as follows. Nouns prototypically function as arguments, but can also serve as predicates and attributes; verbs are normally used as predicates, but can also appear for arguments and attributes; and adjectives are categorically attributes, while secondary they can be used as predicates. The question arises, whether adjectives can serve as arguments (and how). The answer is, undoubtedly, “yes”, they can. When an adjective is used without a head, it begins to function as a noun. The current research aims to describe the morphological behaviour of such nominalised adjectives in the East Caucasian languages. The study of 31 grammatical descriptions of these languages, based on the analysis of nominalised adjectives, reveals 5 groups of the East Caucasian languages.
