Chulym (Russian: Чулымский язык), also known as Chulim, Chulym-Turkic, Küerik, Chulym Tatar or Melets Tatar (not to be confused with the closely related Siberian Tatar language) is the language of the Chulyms. The name the people use to refer to themselves, and also to their language, is Ös, literally ‘self’ or ‘own’. It is also spoken by the Kacik (Kazik, Kuarik). This name originated from a now extinct tribe.
