Hurro-Urartian

Hurro-Urartian is an extinct language family comprising only two known members, Hurrian and Urartian, spoken across ancient Anatolia, the Levant, Mesopotamia and the Zagros Mountains. Hurrian is attested from at least the late third millennium BC until around the end of the second millennium BC, while Urartian, the language of the kingdom of Urartu, is attested from the late 9th century BC to the late 7th century BC. Mainstream linguistic consensus treats Hurro-Urartian as a primary language family with no demonstrated relationship to any other family, though Igor Diakonoff and Sergei Starostin have proposed linking it to the Northeast Caucasian languages within a wider Alarodian grouping, and Arnaud Fornet and Allan Bomhard have separately proposed a connection to Indo-European; neither proposal has gained broad acceptance.
