Located in the Caspian forest south of the capital city of Sāri in Mazandaran, the rural district of Kalijān Rostāq is home to a number of close-knit villages which share a local Mazandarani dialect. The vernacular offers some authentic features in phonology, morphology, and lexis that are otherwise lost in the urban variety spoken in Sāri due to contact with Persian. In an attempt to elucidate on the loosely-known aspects of the Mazandarani language, this study offers a sketch grammar of the dialect of Kalijān Rostāq with a view to typological features. The glossary that follows includes many Caspian cultural items that are already moribund in the language.
