Tatoid dialects
The Tatoid dialects are dialects of the Tati language spoken in the Iranian provinces of Gilan, Qazvin and Alborz.
Tatoid includes the Rudbari, Taleghani and Alamuti dialects. According to Stilo, this special status for this recent type is that these two varieties were originally Tatic which, under the intense influences of Caspian and Persian, have lost all their Tatic grammatical structures.
According to some sources, the people in northern Qazvin speak a dialect of the Tati language. However, other sources state that the people of Alamut are Mazanderani or Gilaks who speak a dialect of the Mazandarani or Gilaki language. According to some linguists, the term ‘Tati’ was used by Turkic speakers to refer to non-turkic speakers. This could explain why some sources refer to the Alamut dialects as Tatoid, while others claim they are Mazandarani or Gilaki. Likely, the ‘Tatoid dialect’ of Alamut is a dialect of Mazandarani or Gilaki, which was labeled as Tati as historically the dialect was considered Mazandarani or Gilaki.
