Tajik, also called Tajiki Persian or Tajiki, is the variety of Persian spoken in Tajikistan and Uzbekistan by Tajiks. It is closely related to neighbouring Dari of Afghanistan with which it forms a continuum of mutually intelligible varieties of the Persian language. Several scholars consider Tajik as a dialectal variety of Persian rather than a language on its own. The popularity of this conception of Tajik as a variety of Persian was such that, during the period in which Tajik intellectuals were trying to establish Tajik as a language separate from Persian, prominent intellectual Sadriddin Ayni counterargued that Tajik was not a "bastardised dialect" of Persian. The issue of whether Tajik and Persian are to be considered two dialects of a single language or two discrete languages has political sides to it.
