Kadaru language  Kadaru (also Kadaro, Kadero, Kaderu, Kodhin, Kodhinniai, Kodoro, Tamya) is a Hill Nubian language spoken in the northern Nuba Mountains in the south of Sudan. It is spoken by around 25,000 people in the Jibaal as-Sitta hills, between Dilling and Delami. It is closely related to Ghulfan, with which it forms the Kadaru-Ghulfan subgroup of Hill Nubian. "Ethnologue" reports that there are six dialects spoken by six clan groups living on six separate hills: Kadaru (Kodur), Kururu (Tagle), Kafir (Ka’e), Kurtala (Ngokra), Dabatna (Kaaral) and Kuldaji (Kendal). The Western form used by the Berko people at Habila (southwest of Jebel Sitta, neighbouring the Ghulfan) may be another dialect or a separate language.
