[5] The term Urum is derived from the Arabic word روم (rūm), meaning Roman and subsequently Byzantine and Greek, with a prothetic u in some Turkic languages.
The word "Urum" involves a prothetic u- that generally appears in Turkic language loanwords initially starting with a r-.
However, the Greek settlers of the Crimea region underwent social and cultural processes, which led to them adopting the Crimean Tatar language as a mother tongue.
[6] Throughout history, they represented an isolated cultural group and rarely settled in towns populated by the Romaioi, despite sharing Greek heritage with them.
Between the fall of the Empire of Trebizond to the Ottomans in 1461 and the Russian annexation of Georgia in 1801 there had been several waves of Pontic Greeks who left the eastern Black Sea coastline and the highlands of the Pontic Alps, and then settled as refugees or economic migrants in Georgia and the South Caucasus.
The largest and most recent waves came in the late 18th and especially the early 19th century, when the South Caucasus experienced mass migrations of Greeks from the Ottoman Empire, mainly from the region of Pontus, as well as the vilayets of Sivas and Erzurum in northeastern Anatolia.
According to Andrei Popov, throughout the 19th century hundreds of Turkish-speaking Greek Orthodox families from Erzurum, Gümüşhane and Artvin moved to Southern Russia and settled on the Tsalka Plateau, in present-day Georgia.
[9] During the Soviet era they populated over 20 villages in Georgia's Tsalka, Dmanisi, Tetritsqaro, Marneuli, and Akhaltsikhe regions.
[11] However some linguists, like Nikolai Baskakov, classify it as a separate Oghuz language due to differences in phonetics, vocabulary and grammar.
No secondary education in Urum Turkish has been available; its speakers attended schools where subjects were taught in Azeri and later in Russian.
[15] A documentation project on the language of Caucasus Urum people compiled a basic lexicon, a sample of translations for the study of grammar, and a text collection.
[16] After the dissolution of the Soviet Union, serious migration did take place, so Greeks are no longer the largest ethnic group in Tsalka.
[5] According to legend common among the Urums of Georgia, long before they left Turkey, the Orthodox Greeks were forced to make a choice between their language and faith.
