The Nilo-Saharan languages are a proposed family of African languages spoken by somewhere around 70 million speakers, mainly in the upper parts of the Chari and Nile rivers, including historic Nubia, north of where the two tributaries of the Nile meet. The languages extend through 17 nations in the northern half of Africa: from Algeria to Benin in the west; from Libya to the Democratic Republic of the Congo in the centre; and from Egypt to Tanzania in the east.
In phonetics, ejective consonants are usually voiceless consonants that are pronounced with a glottalic egressive airstream. In the phonology of a particular language, ejectives may contrast with aspirated, voiced and tenuis consonants. Some languages have glottalized sonorants with creaky voice that pattern with ejectives phonologically, and other languages have ejectives that pattern with implosives, which has led to phonologists positing a phonological class of glottalic consonants, which includes ejectives.
Labial–velar consonants are doubly articulated at the velum and the lips, such as. They are sometimes called "labiovelar consonants", a term that can also refer to labialized velars, such as the stop consonant and the approximant.
Shabo is an endangered language and likely language isolate spoken by about 400 former hunter-gatherers in southwestern Ethiopia, in the eastern part of the South West Ethiopia Peoples' Region.
Implosive consonants are a group of stop consonants with a mixed glottalic ingressive and pulmonic egressive airstream mechanism. That is, the airstream is controlled by moving the glottis downward in addition to expelling air from the lungs. Therefore, unlike the purely glottalic ejective consonants, implosives can be modified by phonation. Contrastive implosives are found in approximately 13% of the world's languages.
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.
Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner. They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation; that is, a second articulation not of the same manner. An example of a doubly articulated consonant is the voiceless labial-velar plosive, which is a and a pronounced simultaneously. On the other hand, the voiceless labialized velar plosive has only a single stop articulation, velar, with a simultaneous approximant-like rounding of the lips. In some dialects of Arabic, the voiceless velar fricative has a simultaneous uvular trill, but this is not considered double articulation either.
The Surmic languages are a branch of the Eastern Sudanic language family.
The Gumuz are an ethnic group speaking a Nilo-Saharan language inhabiting the Benishangul-Gumuz Region in western Ethiopia, as well as the Fazogli region in Sudan. They speak the Gumuz language, which belongs to the Nilo-Saharan family. The Gumuz number around 250,000 individuals.
Unlike many languages, Icelandic has only very minor dialectal differences in sounds. The language has both monophthongs and diphthongs, and many consonants can be voiced or unvoiced.
The Majang people, or Majangir, live in southwestern Ethiopia and speak a Nilo-Saharan language of the Surmic cluster. The 1998 census gave the total of the Majangir population as 15,341, but since they live scattered in the hills in dispersed settlements, their actual total number is undoubtedly much higher. They live around cities of Tepi, Mett'i, and scattered southwest of Mizan Teferi and towards Gambela.
The Majang language is spoken by the Majangir people of Ethiopia. Although it is a member of the Surmic language cluster, it is the most isolated one in the group. A language survey has shown that dialect variation from north to south is minor and does not seriously impede communication. The 2007 Ethiopian Census lists 6,433 speakers for Majang (Messengo), but also reports that the ethnic group consists of 32,822 individuals. According to the census, almost no speakers can be found in Mezhenger Zone of Gambela Region; a total of eleven speakers are listed for the zone, but almost 10,000 ethnic Mejenger or Messengo people.
The Bʼaga languages, also known as Gumuz, form small language family spoken along the border of Ethiopia and Sudan. They have been tentatively classified as closest to the Koman languages within the Nilo-Saharan language family.
The Komuz languages are a proposed branch of the Nilo-Saharan language family which would include the Koman languages, the Gumuz languages and the Shabo language, all spoken in south-eastern Sudan and western Ethiopia. Nilo-Saharan specialists have vacillated on a genealogical relationship between the Koman and Gumuz languages, a relationship called Komuz. Greenberg (1963) had included Gumuz in the Koman language family. Bender classified them together in a distant relationship he called Komuz, but by 1996 he had reversed himself, though he kept both groups in core Nilo-Saharan. Dimmendaal (2008) kept them together, though expressed doubts over whether they belonged in Nilo-Saharan, later referring to Gumuz as an isolate (2011). Ahland, on the basis of new Gumuz data, resurrected the hypothesis. Blench (2010) independently came to the same conclusion and suggested that the Shabo language might be a third, outlying branch. The classification of Shabo is difficult because of a strong Koman influence on the language that is independent of any genealogical relationship between them. Schnoebelen (2009), moreover, sees Shabo as a likely isolate.
Komo is a Nilo-Saharan language spoken by the Kwama (Komo) people of Ethiopia, Sudan and South Sudan. It is a member of the Koman languages. The language is also referred to as Madiin, Koma, South Koma, Central Koma, Gokwom and Hayahaya. Many individuals from Komo are multilingual because they are in close proximity to Mao, Kwama and Oromo speakers. Komo is closely related to Kwama, a language spoken by a group who live in the same region of Ethiopia and who also identify themselves as ethnically Komo. Some Komo and Kwama speakers recognize the distinction between the two languages and culture, whereas some people see it as one "ethnolinguistic" community. The 2007 Ethiopian census makes no mention of Kwama, and for this reason its estimate of 8,000 Komo speakers may be inaccurate. An older estimate from 1971 places the number of Komo speakers in Ethiopia at 1,500. The Komo language is greatly understudied; more information is being revealed as researchers are discovering more data about other languages within the Koman family.
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.
Gwari is a Nupoid language spoken by the Gbagyi people, which make up over a million people in Nigeria. There are two principal varieties, Gbari and Gbagyi, which have some difficulty in communication; sociolinguistically they are distinct languages.
Ot Danum is a Barito language of the central Borneo, Indonesia, spoken by the Ot Danum people. Dialects include Cihie and Dohoi.
Daatsʼiin is a B'aga language of western Ethiopia. There are two communities of speakers in western Ethiopia, one in Mahadid, on the northeast border of Alitash National Park, and one in Inashemsh on the Sudan border, south of the park where the Rahad River crosses from Ethiopia into Sudan.
Medumba phonology is the way in which the Medumba language is pronounced. It deals with phonetics, phonotactics and their variation across different dialects of Medumba.
