Korku language
The Korku language is the language of the Korku tribe of central India. It belongs to the Kolarian or Munda family, isolated in the midst of a Dravidian (Gondi) population.
Korkus are also closely associated with the Nihali people, many of whom have traditionally lived in special quarters of Korku villages. Korku is spoken by half a million people, mainly in four districts of southern Madhya Pradesh (Khandwa, Harda, Betul, Hoshangabad) and three districts of northern Maharashtra (Rajura and Korpana tahsils of Chandrapur district, Manikgarh pahad area near Gadchandur in Chandrapur district) (Amravati, Buldana, Akola). Korku is spoken in a declining number of villages and is gradually being replaced by Hindi.
Etymology
The name Korku comes from Koro-ku (-ku is the animate plural), Koro 'person, member of the Korku community' (Zide 2008).
Varieties
Zide (2008:256) lists the following dialects.
Kurku proper is spoken in the west. Most available data is from the Melghat subdialect. Other subdialects include Betul-Hoshangabad. The Lahi variety of Hoshangabad is notable for its loss of the dual.
