Mazanderani

Mazanderani (Mazeruni: مازِرونی; also referred to as Mazani (مازنی), Tabari (تبری) or Taveri, Tati, Geleki and Galeshi) is an Iranian language of the Northwestern branch spoken by the Mazanderani people. As of 2023, there were 1.35 million native speakers. As a member of the Northwestern branch (the northern branch of Western Iranian), etymologically speaking, it is rather closely related to Gilaki and also related to Persian, which belongs to the Southwestern branch. Though the Mazani and Persian languages have both influenced each other to a great extent, both are independent languages with different origins in the Iranian plateau.

Mazandarani is closely related to Gilaki, and the two languages have similar vocabularies. The Gilaki and Mazandarani languages (but not other Iranian languages) share certain typological features with Caucasian languages (specifically the non-Indo-European South Caucasian languages), reflecting the history, ethnic identity, and close relatedness to the Caucasus region and Caucasian peoples of Mazandaranis and Gilak people.
