Modern Greek (Νεοελληνική γλώσσα) is the only official language of the Hellenic Republic, and is spoken by some 99.5% of the population by approximately 11,100,000 people[3] (though not necessarily as a first language). Standard Modern Greek is the officially used standard, but there are several non-official dialects and distinct Hellenic languages spoken as well. With regional spoken dialects existing side by side with learned, archaic written forms. All surviving forms of modern Greek, except the Tsakonian dialect, are descendants of the common supra-regional (Koine) as it was spoken in late antiquity. As such, they can ultimately be classified as descendants of Attic Greek, the dialect spoken in and around Athens in the classical era. Tsakonian, an isolated dialect spoken today by a dwindling community in the Peloponnese, is a descendant of the ancient Doric dialect. Some other dialects have preserved elements of various ancient non-Attic dialects, but Attic Koine is nevertheless regarded by most scholars as the principal source of all of them.
