Dolgan is a severely endangered Turkic language spoken in the extreme north of the Russian Federation which has undergone noticeable substrate influence and thus exhibits grammatical structures differing from other Turkic languages. The grammar at hand is the first fully-fledged grammar of Dolgan in English language: It describes the Dolgan language system from an internal perspective basing on corpus data of natural Dolgan speech. It takes historical, comparative and typological perspectives, if applicable, but refrains from pertaining to a particular linguistic theory. Consequently, both Turcologists and general linguists can make use of it independently from their individual research question.
