the Volga river (The Belaya + the Kama + Middle and Lower Volga) · a male given name from the Turkic languages · a male character in Ural-batyr, Bashkir folk epic
köken: Cognate with Old Uyghur [script needed] (Etil, “a river name, presumably the Volga”). Compare also with Turkish İdil; and Atil, the name of the capital of historical Khazaria, situated in the Volga delta. Theophanes the Confessor in the 9th century mentions the river as Ancient Greek Ατελ (Atel). Thus, it is still debatable if the river name is Turkic or pre-Turkic by origin.
