The Kordofanian languages are a geographic grouping of five language groups spoken in the Nuba Mountains of the South Kordofan region of Sudan: Talodi–Heiban languages, Lafofa languages, Rashad languages, Katla languages and Kadu languages. The first four groups are sometimes regarded as branches of the hypothetical Niger–Congo family, whereas Kadu is now widely seen as a branch of the proposed Nilo-Saharan family.
The Daju languages are spoken in isolated pockets by the Daju people across a wide area of Sudan and Chad. In Sudan, they are spoken in parts of the regions of Kordofan and Darfur, in Chad they are spoken in Wadai. The Daju languages belong to the Eastern Sudanic subfamily of Nilo-Saharan.
Berta proper, a.k.a. Gebeto, is spoken by the Berta in Sudan and Ethiopia. As of 2006 Berta had approximately 180,000 speakers in Sudan.
The Teda language, also known as Tedaga, Todaga, Todga, or Tudaga is a Nilo-Saharan language spoken by the Teda, a northern subgroup of the Toubou people who inhabit southern Libya, northern Chad and eastern Niger. A small number also inhabit northeastern Nigeria.
The Kadu languages, also known as Kadugli–Krongo or Tumtum, are a small language family of the Kordofanian geographic grouping, once included in Niger–Congo. However, since Thilo Schadeberg (1981), Kadu is widely seen as Nilo-Saharan. Evidence for a Niger-Congo affiliation is rejected, and a Nilo-Saharan relationship is controversial. A conservative classification would treat the Kadu languages as an independent family.
The Shatt language is a Daju language of the Eastern Daju family spoken by the Shatt people in the Shatt Hills southwest of Kaduqli in South Kurdufan province in southern Sudan.
Rendille is an Afro-Asiatic language spoken by the Rendille people inhabiting northern Kenya. It is part of the family's Cushitic branch.
Temein, also known as Ron(g)e, is an Eastern Sudanic language spoken by the Temein people of the Nuba Hills in Sudan.
Jarawan is a group of languages spoken mostly in Bauchi State, Nigeria, with some also scattered in Plateau State, Taraba State, and Adamawa State in the same country. Two related languages formerly spoken in Cameroon are now extinct but are believed to have belonged to the group. This connection between Nigerian and Cameroonian Jarawan is attributed to Thomas (1925). Whether Jarawan languages are best classified alongside other Bantu languages or among non-Bantu Bantoid languages is a matter of ongoing debate. A number of descriptions and classifications in the early 20th century suggest that they be may historically related to Bantu languages but not necessarily Bantu themselves. Other perspectives based on lexicostatistic modeling and other phylogenetic techniques for language comparison argue instead that Jarawan languages are properly classified alongside Zone A Bantu languages (A31-A40-A60). For classifications based on these more recent studies, see for example Blench (2006), Piron (1997), and Grollemund (2012).
The Keiga people are a sub-ethnic group of the Nuba peoples in the Nuba Mountains of South Kordofan state, in southern Sudan. The population of this ethnicity likely is below 10,000. They speak Keiga, a Nilo-Saharan language. The language belongs to the Kadugli–Krongo family.
Krongo, also spelled Korongo or Kurungu and known as Dimodongo, Kadumodi, or Tabanya after local towns, is a Kadu language spoken in the South West of the Nuba Mountains in South Kordofan, Sudan.
Moro is a Kordofanian language spoken in the Nuba Mountains of South Kordofan, Sudan. It is part of the Western group of West Central Heiban Kordofonian languages and belongs to the Niger-Congo phylum. In 1982 there were an estimated 30,000 Moro-speakers. This was before the second Sudan civil war and therefore the recent number of speakers might differ. There can be noted an influence of Arabic and it is suspected that today approximately a fourth of all Moro vocabulary has a relation or an origin in the Arabic language.
The East Kainji languages are spoken in a compact area of the Jos Plateau in Nigeria, near Jos. There are more than 20 of them, most of which are poorly studied.
Nyimang, also known as Ama, is an East Sudanic language spoken in the Nuba Mountains of Sudan by the Nyimang people who are a sub-group of the Nuba people.
Afitti is a language spoken on the eastern side of Jebel el-Dair, a solitary rock formation in the North Kordofan province of Sudan. Although the term ‘Dinik’ can be used to designate the language regardless of cultural affiliation, people in the villages of the region readily recognize the terms ‘Ditti’ and ‘Afitti.’ There are approximately 4,000 speakers of the Afitti language and its closest linguistic neighbor is the Nyimang language, spoken west of Jebel el-Dair in the Nuba Mountains of the South Kordofan province of Sudan.
The Otoro language classifies in to the Haiban Language family which belongs to the Kordofanian Languages and therefore it is a part of the Niger-Congo Languages. In a smaller view the Otoro is a segment of the „central branch “ from the so-called Koalib-Moro Groupe of the Languages which are spoken in the Nuba Mountains. The Otoro language is spoken within the geographical regions encompassing Kuartal, Zayd and Kauda in Sudan. The precise number of Otoro speakers is unknown, though current evaluates suggest it to be exceeding 15000 individuals.
Keiga Jirru is an Eastern Sudanic language spoken in the Nuba Hills of Sudan.
Kare is a southern Mbum language of the Central African Republic, spoken by the Kare people in the mountains of the northeasterly Ouham-Pendé prefecture around Bocaranga. It is spoken by around 97,000 people in the country, and another few thousand speakers in Cameroon. The language's presence on the southeastern edge of the Mbum family is thought to reflect early 19th-century migrations from the Adamawa Plateau, fleeing Fulani raids.
Birri (Bviri) is a nearly extinct, possibly Central Sudanic language of CAR and South Sudan. According to Boyeldieu (2010), its classification as Central Sudanic has yet to be demonstrated, but Starostin (2016) finds its closest relative to be Kresh.
The Nuba Mountains, located in the West Kordofan and South Kordofan states in the south of Sudan, are inhabited by a diverse set of populations speaking various languages not closely related to one another.
