The Tatoid dialects, also known as the Tabaroid dialects, South Alborz varieties, or simply as Deylami,"Although the term “Deylami” is most closely associated with South Alborz varieties spoken in the region known as Deylam in the early Islamic Period, which stretched across a mountainous area from present-day south-east Gilan to Komis or Qumes (present-day Semnan Province), it is also still sometimes used to refer to Gālesh Gilaki varieties at the western end of this region, and by extension, Eastern Gilaki as a whole." Atlas of the Languages of Iran. Retrieved 04-03-2026 are dialects of the Tatic group of Northwestern Iranian languages spoken in the Iranian provinces of Gilan, Qazvin and Alborz. Tatoid includes the Rudbari (not to be confused with Rudbaraki, related to Gilaki), Taleqani and Alamuti dialects, among others. According to Stilo, Rudbari and Taleqani were originally dialects of the Tati language which, under the intense influences of Caspian and Persian, lost all the structural hallmarks of Tati.
Alamuti dialect
According to some sources, the people in northern Qazvin (Alamut) speak a dialect of the Tati language.مقدمه کتاب «دستور زبان گویش‌های تاتی جنوبی»، پروفسور احسان یارشاطر، لاهه - پاریس ١٩٦٩گونه‌های زبانی تاتی، دونالد استیلو، ۱۹۸۱مقاله «بررسی گویش تاتی الموت»، پرویز البرزی ورکی، ۱۳۷۰، دانشگاه تهران 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.واژۀ تات را مردم ترک زبان به همسایگان غیرترک خود اطلاق می کردند. برخی تات را مترادف تازیک و تاجیک (یعنی فارسی زبان) دانسته ان دانشنامه اسلامید.نامی که ترک ها به ایرانیان و کسانی که در سرزمین ترکان و یا سرزمین های تحت استیلای ترکان به سر می بردند... اند، فرهنگ عمیدبه گروههای مختلف از اقوام غیرترک اطلاق شده:۱ - طبق قول مندرج دردیوان لغات الترک (۲۲۴) این نام نزد همه ترکان در مورد ایرانیان بکار میرفته جلال الدین مولوی هم دراشعار ترکی خود این نام را به ایرانیان اطلاق کرده. While the ‘Tatoid dialect’ of Alamut has been postulated to be a dialect of Mazandarani, the ASI and Glottlog place it under the Tatic group.
