The Greek element in Cappadocian is to a large extent Byzantine, e.g. θír or tír "door" from (Ancient and) Byzantine Greek θύρα (Modern Greek θύρα), píka or épka "I did" from Byzantine Greek έποικα (Modern Greek έκανα). Other, pre-Byzantine, archaisms are the use of the possessive pronouns mó(n), só(n) etc. from Ancient Greek εμός, σός etc. and the formation of the imperfect by means of the suffix -išk- from the Ancient Greek (Ionic) iterative suffix -(e)sk-. Turkish influence appears at every level. The Cappadocian sound system includes the Turkish vowels ı, ö, ü, and the Turkish consonants b, d, g, š, ž, tš, dž (although some of these are also found in Greek words as a result of palatalization).
Turkish vowel harmony is found in forms such as düšündǘzu "I think", aor. 3sg düšǘntsü < düšǘntsi (Malakopi), from Turkish düşünmek, patišáxıs < patišáxis "king" (Delmeso), from Turkish padişah. Cappadocian noun morphology is characterized by the emergence of a generalized agglutinative declension and the progressive loss of grammatical gender distinctions, e.g. to néka "the (neuter) woman (feminine)", genitive néka-ju, plural nékes, genitive nékez-ju (Ulağaç). Another Turkish feature is the morphological marking of definiteness in the accusative case, e.g. líkos "wolf (nominative / unmarked indefinite accusative)" vs. líko "wolf (marked definite accusative)".
Agglutinative forms are also found in the verb system such as the pluperfect írta ton "I had come" (lit. "I came I was") (Delmeso) on the model of Turkish geldi idi (geldiydi). Although Cappadocian word order is essentially governed by discourse considerations such as topic and focus, there is a tendency towards the Turkish subject–object–verb word order with its typological correlates (suffixation and pre-nominal grammatical modifiers).
The commonality among all Greek Cappadocian dialects is that they evolved from Byzantine Greek under the influence of Turkish. On the other hand, those dialects evolved in isolated villages. This has resulted in a variety of Greek Cappadocian dialects.
