The aim of this study is to examine the formation of the feminine form of adjectives in Northern Greek dialects within the broader context of Modern Greek dialects and their historical evolution. It is based on two observations concerning Greek adjectives: (a) Greek belongs to the group of languages that exhibit gender distinction in adjectives (Dixon 2004) and (b) Greek exhibits a rising tendency towards registering gender distinction morphologically over time (Tzitzilis forthcoming a) We first examine the formation of feminine occupational nouns, andronymics (feminine nouns designating the wife of someone) and feminine nouns for denoting female animals and then investigate the feminine form of adjectives (inflectional and derivational morphemes) in Northern dialects, as well as the factors that determine the distribution of these morphemes. The findings of our study suggest that (a) certain morphemes are common across all categories; (b) the expression of the feminine form of adjectives exhibits variation organized around morphological bundles (in Tzitzilis’ terms); and (c) as concerns the formation of the feminine form of adjectives, the main differences of Northern dialects from other non-Asia Minor dialects are due to language contact.
