Kadugli language

Kadugli, also Katcha-Kadugli-Miri or Central Kadu, is a Kadu language or dialect cluster of the Nilo-Saharan language family spoken in South Kordofan, Sudan. Stevenson treats the varieties as dialects of one language, and they share a single ISO code, though Schadeberg (1989) treats them as separate languages.

Dialects
There are five commonly cited varieties. Three of them are rather divergent, on the verge of being distinct languages: However, they share a single orthography and use the same literacy materials (Ethnologue).
 * Katcha (Tolubi, Dholubi)
 * Kadugli proper (Dakalla, Talla, Dhalla, Toma Ma Dalla, Kudugli, Morta)
 * Miri

Of the two other commonly cited varieties, Damba is somewhat closer to Kadugli, while Tumma appears to be a (sub)dialect of Katcha.

Villages in which the dialects are spoken according to the 22nd edition of Ethnologue:
 * Katcha dialect: Belanya, Dabakaya, Farouq, Kafina, Katcha, and Tuna villages
