Dhimotiki

Demotic Greek (Greek: δημοτική γλώσσα [ðimotiˈci], "language of the people") or dimotiki is the modern vernacular form of the Greek language. The term has been in use since 1818.Demotic refers particularly to the form of the language that evolved naturally from Ancient Greek, in opposition to the artificially archaic Katharevousa, which was the official standard until 1976. The two complemented each other in a typical example of diglossia until the resolution of the Greek language question in favour of Demotic.

Demotic Greek differs from varieties of Ancient Greek and learned forms inherited from the same in several important ways. Syntactically, it favors parataxis over subordination. It also heavily employs redundancy, such as (small little girl) and (he went back to sleep again). Somewhat in connection with this, Demotic employs the diminutive with great frequency, to the point that many Demotic forms are in effect neuter diminutives of ancient words, especially irregular ones, e.g. νήσι(ον) (island) from ancient ἡ νήσος (island, an irregular noun that had feminine gender but masculine declension).

Greek noun declensions underwent considerable alteration, with irregular and less productive forms being gradually replaced by more regular forms based on the old one: άντρας (man) for ancient ἄνηρ. Another feature was the merging of classical accusative and nominative forms, distinguishing them only by their definite articles, which continued to be declined as in Ancient Greek. This was especially common with nouns of the third declension, such as (hometown, fatherland) which became nominative η πατρίδα, accusative τη πατρίδα in Demotic. Another feature of the evolution of Demotic was the near-extinction of the genitive plural, which was revived in Katharevousa and is now productive again in Demotic.
