The Cushitic languages are a branch of the Afroasiatic language family. They are spoken primarily in the Horn of Africa, with minorities speaking Cushitic languages to the north in Egypt and Sudan, and to the south in Kenya and Tanzania. As of 2012, the Cushitic languages with over one million speakers were Oromo, Somali, Beja, Afar, Hadiyya, Kambaata, and Sidama.
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.
The number of languages natively spoken in Africa is variously estimated at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages, one of the greatest concentrations of linguistic diversity in the world. The languages of Africa belong to many distinct language families, among which the largest are:
The Nilotic peoples are people indigenous to the Nile Valley who speak Nilotic languages. They inhabit South Sudan, Sudan, Ethiopia, Uganda, Kenya, the eastern border area of Democratic Republic of the Congo, Rwanda, Burundi and Tanzania. Among these are the Burun-speaking peoples, Teso people also known as Iteso or people of Teso, Karo peoples, Luo peoples, Ateker peoples, Kalenjin peoples, Karamojong people also known as the Karamojong or Karimojong, Datooga, Dinka, Nuer, Atwot, Lotuko, and the Maa-speaking peoples.
The Kakwa people are a Nilotic ethnic group and part of the Karo people found in north-western Uganda, south-western South Sudan, and north-eastern Democratic Republic of the Congo, particularly to the west of the White Nile river.
The Luo, are several ethnically and linguistically related Nilotic ethnic groups that inhabit an area ranging from Egypt and Sudan to South Sudan and Ethiopia, through Northern Uganda and eastern Congo (DRC), into western Kenya, and the Mara Region of Tanzania. Their Luo languages belong to the western branch of the Nilotic language family.
The Bantu expansion was a major series of migrations of the original Proto-Bantu-speaking group, which spread from an original nucleus around West-Central Africa. In the process, the Proto-Bantu-speaking settlers displaced, eliminated or absorbed pre-existing hunter-gatherer and pastoralist groups that they encountered.
The Kalenjin are a group of tribes indigenous to East Africa, residing mainly in what was formerly the Rift Valley Province in Kenya and the Eastern slopes of Mount Elgon in Uganda. They number 6,358,113 individuals per the Kenyan 2019 census and an estimated 273,839 in Uganda according to the 2014 census mainly in Kapchorwa, Kween and Bukwo districts.
The Abagusii are a Bantu ethnic group and nation indigenous to Kisii and Nyamira counties of former Nyanza, as well as parts of Kericho and Bomet counties of the former Rift Valley province of Kenya.
Christopher Ehret, who currently holds the position of Distinguished Research Professor at UCLA, is an American scholar of African history and African historical linguistics particularly known for his efforts to correlate linguistic taxonomy and reconstruction with the archeological record. He has published ten books, most recently History and the Testimony of Language (2011) and A Dictionary of Sandawe (2012), the latter co-edited with his wife, Patricia Ehret. He has written around seventy scholarly articles on a wide range of historical, linguistic, and anthropological subjects. These works include monographic articles on Bantu subclassification; on internal reconstruction in Semitic; on the reconstruction of proto-Cushitic and proto-Eastern Cushitic; and, with Mohamed Nuuh Ali, on the classification of the Soomaali languages. He has also contributed to a number of encyclopedias on African topics and on world history.
The Nilotic languages are a group of related languages spoken across a wide area between South Sudan and Tanzania by the Nilotic peoples.
The Western Nilotic languages are one of the three primary branches of the Nilotic languages, along with the Eastern Nilotic languages and Southern Nilotic languages; Themselves belonging to the Eastern Sudanic subfamily of Nilo-Saharan. The about 22 Western Nilotic languages are spoken in an area ranging from southwestern Ethiopia and South Sudan via northeastern Democratic Republic of the Congo and northern Uganda to southwestern Kenya.
The Southern Nilotic languages are spoken mainly in western Kenya and northern Tanzania. They form a division of the larger Nilotic language family, along with the Western Nilotic languages and the Eastern Nilotic languages.
The Kuliak languages, also called the Rub languages, are a group of languages spoken by small relict communities in the mountainous Karamoja region of northeastern Uganda.
In Uganda the most spoken language in the capital city is Luganda, followed by English, as all schools in Uganda use it in their studies due to the introduction of English during the colonial period. English is also the language of business and judicial matters. Most spoken after Luganda and English is Swahili. This language is more common in neighbouring Kenya and Tanzania. Swahili is taught in schools as an optional additional language and it is mostly spoken by the Ugandan army. In 2005, there were talks to include Swahili as the second official language as it was seen as neutral, however this is still not ratified by the government. Swahili is used among some communities bordering South Sudan and Kenya.
Datooga is a Nilotic language or dialect cluster of the Southern Nilotic group. It is spoken by the Datooga people of the Great Rift Valley of Tanzania. The Sukuma name Taturu is also sometimes used in English; the Swahili name Mang'ati comes from Maasai, where it means "enemy". However, it is not considered offensive to the Datooga, as there is a degree of pride in being the historic enemy of the Maasai, and Mang'ati has become the standard name for the group in Swahili. In addition, numerous tribal and dialectal names may be found for the people or language as a whole.
The Proto-Afroasiatic homeland is the hypothetical place where speakers of the Proto-Afroasiatic language lived in a single linguistic community, or complex of communities, before this original language dispersed geographically and divided into separate distinct languages. Afroasiatic languages are today mostly distributed in parts of Africa, and Western Asia.
South Sudan is home to around 60 indigenous ethnic groups and 80 linguistic partitions among a 2021 population of around 11 million. Historically, most ethnic groups were lacking in formal Western political institutions, with land held by the community and elders acting as problem solvers and adjudicators. Today, most ethnic groups still embrace a cattle culture in which livestock is the main measure of wealth and used for bride wealth.
The Bantu peoples are an ethnolinguistic grouping of approximately 400 distinct native African ethnic groups who speak Bantu languages. The languages are native to 24 countries spread over a vast area from Central Africa to Southeast Africa and into Southern Africa.
The Kalenjin people are an ethnolinguistic group indigenous to East Africa, with a presence, as dated by archaeology and linguistics, that goes back many centuries. Their history is therefore deeply interwoven with those of their neighboring communities as well as with the histories of Kenya, Uganda, Tanzania, South Sudan, and Ethiopia.
