Tajik

Tajik, Tajik Persian, Tajiki Persian, also called Tajiki, is the variety of Persian spoken in Tajikistan and Uzbekistan by ethnic 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 issue of whether Tajik and Persian are to be considered two dialects of a single language or two discrete languages has political aspects to it.

By way of Early New Persian, Tajik, like Iranian Persian and Dari Persian, is a continuation of Middle Persian, the official administrative, religious and literary language of the Sasanian Empire (224–651 CE), itself a continuation of Old Persian, the language of the Achaemenid Empire (550–330 BC).
