Ossetians
The Ossetians or Ossetes (; , '; дигорæ, дигорæнттæ, ') are an Iranian ethnic group of the Caucasus Mountains, indigenous to the ethnolinguistic region known as Ossetia.
They speak Ossetic, an Eastern Iranian (Alanic) language of the Indo-European languages family, with most also fluent in Russian as a second language. The Ossetian language is neither closely related to nor mutually intelligible with any other language of the family today. Ossetic, a remnant of the Scytho-Sarmatian dialect group which was once spoken across the Pontic–Caspian Steppe, is one of the few Iranian languages inside Europe.
