This is the first thorough description of the Nakh-Daghestanian language Hinuq. Hinuq has about 600 speakers living primarily in a single village in the Caucasus mountains in southern Russia (Daghestan). During several fieldwork trips, the author collected an extensive corpus of texts. Based on the data, Forker provides a comprehensive analysis of Hinuq grammar with reference to other Nakh-Daghestanian languages, to Caucasian studies and to typological and general linguistic topics.
