Old Turkic (also
East Old Turkic,
Orkhon Turkic,
Old Uyghur) is the earliest attested form of
Turkic, found in
Göktürk and
Uyghur inscriptions dating from about the 7th century to the 13th century. It is the oldest attested member of the Orkhon branch of Turkic, which is extant in the modern
Western Yugur language. Confusingly, it is not the ancestor of the language now called
Uighur; the contemporaneous ancestor of Uighur to the west is called
Middle Turkic.
