Determining the origins and nature of the Khazars is closely bound with theories of their languages, but it is a matter of intricate difficulty since no indigenous records in the Khazar language survive, and the state was polyglot and polyethnic. Whereas the royal or ruling elite probably spoke an eastern variety of Shaz Turkic, the subject tribes appear to have spoken varieties of Lir Turkic, such as Oğuric, a language variously identified with Bulğaric, Chuvash, and Hunnish.

The latter based upon the assertion of the Persian historian Istakhri the Khazar language was different from any other known tongue. Alano-As was also widely spoken. Eastern Common Turkic, the language of the royal house and its core tribes, in all likelihood remained the language of the ruling elite in the same way that Mongol continued to be used by the rulers of the Golden Horde, alongside of the Qipčaq Turkic speech spoken by the bulk of the Turkic tribesmen that constituted the military force of this part of the Činggisid empire. Similarity, Oğuric, like Qipčaq Turkic in the Jočid realm, functioned as one of the languages of government. One method for tracing their origins consists in the analysis of the possible etymologies behind the ethnonym "Khazar".
