to the uniformity of Common Turkic, which Al-Istakhri mentioned "as for the Turks, all of them, from the Toquz Oghuz, Qirgiz, Kimek, Oguz, Qarluq, their language is one. They understand one another”. Even if Khazar belonged or was similar to Oghuro-Bulgaric languages, it was distinctly different. The linguistic data consists of Khazar titles (Beg, Bolušči, Ishad, Il-teber/El-teber, Qağan, Kündü Qağan, Jâwšîġr, Tarxan, Tudun, Yabgu, Yilig/Yelig), anthroponyms (Itaq), and toponyms (Sarkel/Šarkil, Sarığšın/Sarığčın), mostly of Turkic origin. The interpretations do not indicate whether these are Common Turkic or Oghuric. Vocabulary With only one grammatical form attested—oqurüm, "I have read"—Khazar was stated by the 1986 Guinness Book of Records to have the "smallest literature" of any language.
