Tajik is a Persian language spoken primarily in Tajikistan and Uzbekistan, as well as by diaspora communities in Russia and other countries. It is closely related to Persian (Farsi) and Dari, with which it shares mutual intelligibility to a significant extent. Tajik is written using the Cyrillic script in Tajikistan, whereas in Uzbekistan and among diaspora communities, it is often written using the Perso-Arabic script.
