Gumuz is a small language family spoken along the border of Ethiopia and Sudan. It has been tentatively classified within the Nilo-Saharan family, perhaps closest to the Koman languages.

Languages

There are three or four Gumuz languages. Grammatical forms are distinct between Northern Gumuz and Southern Gumuz. Yaso is at least a divergent dialect, perhaps distinct enough to count as a separate language. Daats'iin, discovered in 2013, is closest to Southern Gumuz.

Classification

Dimmendaal (2008) notes that mounting grammatical evidence has made the Nilo-Saharan proposal as a whole more sound since Greenberg proposed it in 1963, but that such evidence has not been forthcoming for Songhay, Koman, and Gumuz: "very few of the more widespread nominal and verbal morphological markers of Nilo-Saharan are attested in the Coman languages plus Gumuz ... Their genetic status remains debatable, mainly due to lack of more extensive data." (2008:843) And later, "In summarizing the current state of knowledge, ... the following language families or phyla can be identified — ... Mande, Songhai, Ubangian, Kadu, and the Coman languages plus Gumuz." (2008:844)

This "Coman plus Gumuz" is what Greenberg (1963) had subsumed under Koman and what Bender (1989) had called Komuz, a broader family consisting of Gumuz and the Koman languages. However, Bender (2000) separated Gumuz as at least a distinct branch of Nilo-Saharan, and suggested that it might even be a language isolate. Dimmendaal (2000), who tentatively included Koman within Nilo-Saharan, excluded Gumuz as an isolate, as it did not share the tripartite singulative–collective–plurative number system characteristic of the rest of the Nilo-Saharan language families. Ahland (2010, 2012), however, reports that with better attestation, Gumuz does indeed appear to be Nilo-Saharan, and perhaps closest to Koman. It has grammatical forms that resemble what might be expected from an ancestral proto-Nilo-Saharan language. Gumuz may thus help elucidate the family, which is extremely diverse and has been difficult to substantiate.
