# Koman languages

The Koman languages are a small, close-knit family of languages located along the Ethiopia–Sudan border with about 50,000 speakers. They are conventionally classified as part of the Nilo-Saharan family. However, due to the paucity of evidence, many scholars treat it as an independent language family. Among scholars who do accept its inclusion within Nilo-Saharan, opinions vary as to their position within it.
Koman languages in Ethiopia are in close contact with the Omotic Mao languages. In Ethiopia, some Koman-speaking groups also consider themselves to be ethnically Mao.

## Internal classification

The Koman languages are:
* Koman
** Uduk, or T’wampa, (formerly in South Sudan) — about 20,000 speakers, most at a large refugee camp at Bonga, near Gambela
** Kwama (Ethiopia) — about 15,000 speakers, mainly in Benishangul-Gumuz
** Komo (Sudan) — about 12,000 speakers mainly in An Nil al Azraq
** Opuuo (Opo), or Shita (Ethiopia) — spoken in 5 villages north of the Nuer by about 5,000 people
** Dana, a newly discovered language located near Opo
** ?Gule (Sudan) — extinct
The poorly known Shabo language (600 speakers) shows strong Koman influence, and it has been suggested (on little evidence) that it may be a Koman language. Gule is generally classified as Koman, but the evidence is as yet insufficient.

### Otero (2019)

Otero's (2019: 28) internal classification of Koman:
* Koman
** Gwama
*** Highland Gwama
*** Lowland Gwama
** Central
*** Komo–Uduk
**** Komo
**** Uduk
***** Chali
***** Yabus
*** Dana–Opo
**** Dana
**** Opo
***** [clade]
****** Bilugu
****** Modin
***** [clade]
****** Pame
****** Kigile

## External 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, Gumuz, and Koman: "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) However, Ahland (2010) reports that with better attestation, both Koman and Gumuz do appear to be Nilo-Saharan, and perhaps closest to each other.

## Reconstruction

Proto-Koman has been reconstructed by Lionel Bender (1983) and Otero (2019).
