Modern Greek (Νέα Ελληνικά, Néa Elliniká, ˈne.a eliniˈka or Κοινή Νεοελληνική Γλώσσα, Kiní Neoellinikí Glóssa), generally referred to by speakers simply as Greek (Ελληνικά, Elliniká), refers collectively to the dialects of the Greek language spoken in the modern era, including the official standardized form of the languages sometimes referred to as Standard Modern Greek. The end of the Medieval Greek period and the beginning of Modern Greek is often symbolically assigned to the fall of the Byzantine Empire in 1453, even though that date marks no clear linguistic boundary and many characteristic features of the modern language arose centuries earlier, beginning around the fourth century AD.
During most of the Modern Greek period, the language existed in a situation of diglossia, with regional spoken dialects existing side by side with learned, more archaic written forms, as with the vernacular and learned varieties (Dimotiki and Katharevousa) that co-existed in Greece throughout much of the 19th and 20th centuries.
Varieties of Modern Greek
Varieties of Modern Greek include Demotic, Katharevousa, Pontic, Cappadocian, Mariupolitan, Southern Italian, Yevanic, and Tsakonian.
Demotic Greek
Strictly speaking, Demotic or Dimotiki (Δημοτική), refers to all popular varieties of Modern Greek that followed a common evolutionary path from Koine and have retained a high degree of mutual intelligibility to the present. As shown in Ptochoprodromic and Acritic poems, Demotic Greek was the vernacular already before the 11th century and called the "Roman" language of the Byzantine Greeks, notably in peninsular Greece, the Greek islands, coastal Asia Minor, Constantinople, and Cyprus.
Today, a standardized variety of Demotic Greek is the official language of Greece and Cyprus, and is referred to as "Standard Modern Greek", or less strictly simply as "Greek", "Modern Greek", or "Demotic".
Demotic Greek comprises various regional varieties with minor linguistic differences, mainly in phonology and vocabulary.
