Amdang (also Biltine; autonym: sìmí amdangtí) is a language closely related to Fur, which together constitute a branch of the Nilo-Saharan language family. It is mainly spoken in Chad, north of the town of Biltine, and sporadically elsewhere in Ouaddaï Region. There are also small colonies of speakers in Darfur near Woda'a and Fafa, and in Kordofan in the district and at Magrur north of Bara. Most of the ethnic group now speaks Arabic. Wolf (2010) provides lexical data for the Kouchane, Sounta, Yaouada, and Tere dialects of Amdang.
