Griko, sometimes spelled Grico, is the dialect of Italiot Greek spoken by Griko people in Salento (province of Lecce), and also called Grecanico, in Calabria. Some Greek linguists consider it to be a Modern Greek dialect and often call it (Κατωιταλιώτικα, "Southern Italian") or (Γραικάνικα), whereas its own speakers call it (Γκραίκο, in Calabria) or (Γκρίκο, in Salento). is spoken in Salento while is spoken in Calabria. Griko and Standard Modern Greek are partially mutually intelligible.
The most popular hypothesis on the origin of Griko is the one by Gerhard Rohlfs and Georgios Hatzidakis, that Griko's roots go as far back in history as the time of the ancient Greek colonies in Southern Italy and Sicily in the eighth century BC. The Southern Italian dialect is thus considered to be the last living trace of the Greek elements that once formed Magna Graecia.
There are, however, competing hypotheses according to which Griko may have preserved some Doric elements, but its structure is otherwise mostly based on Koine Greek, like almost all other Modern Greek dialects. Thus, Griko should rather be described as a Doric-influenced descendant of Medieval Greek spoken by those who fled the Byzantine Empire to Italy trying to escape the Turks. The idea of Southern Italy's Greek dialects being historically derived from Medieval Greek was proposed for the first time in the 19th century by Giuseppe Morosi.
Two small Italiot Greek-speaking communities survive today in the Italian regions of Calabria (Metropolitan city of Reggio Calabria) and Apulia (Province of Lecce). The Italiot Greek-speaking area of Apulia comprises nine small towns in the Grecìa Salentina region (Calimera, Martano, Castrignano de' Greci, Corigliano d'Otranto, Melpignano, Soleto, Sternatia, Zollino, Martignano), with a total of 40,000 inhabitants. The Calabrian Greek region also consists of nine villages in Bovesia, (including Bova Superiore, Roghudi, Gallicianò, Chorìo di Roghudi and Bova Marina) and four districts in the city of Reggio Calabria, but its population is significantly smaller, with around only 2000 inhabitants.
