The Afroasiatic languages, also known as Hamito-Semitic, or Semito-Hamitic, and sometimes also as Afrasian, Erythraean or Lisramic, are a language family of about 300 languages that are spoken predominantly in Western Asia, North Africa, the Horn of Africa, and parts of the Sahara/Sahel. With the exception of its Semitic branch, all other branches of the Afroasiatic family are spoken exclusively on the African continent.
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 the 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, Saho, and Sidama.
The Nilo-Saharan languages are a proposed family of African languages spoken by some 50–60 million people, 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 Nilotic peoples are people indigenous to the Nile Valley who speak Nilotic languages. They inhabit South Sudan, Sudan, Ethiopia, Uganda, Kenya, the Democratic Republic of the Congo, Rwanda,and Tanzania. Among these are the Burun-speaking peoples, Karo peoples, Luo peoples, Ateker peoples, Kalenjin peoples, Datooga, Dinka, Nuer, Atwot, Lotuko, and the Maa-speaking peoples.
Nubians are an ethnic group indigenous to the region which is now northern Sudan and southern Egypt. They originate from the early inhabitants of the central Nile valley, believed to be one of the earliest cradles of civilization. In the southern valley of Egypt, Nubians differ culturally and ethnically from other Egyptians, although they intermarried with members of other ethnic groups, especially Arabs. They speak Arabic and Nubian languages, part of the Northern Eastern Sudanic languages.
The Luo, are several ethnically and linguistically related Nilo-Semitic 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 is a hypothesis of major series of migrations of the original Proto-Bantu-speaking group, which spread from an original nucleus around Central Africa across much of sub-Saharan Africa. In the process, the Proto-Bantu-speaking settlers displaced or absorbed pre-existing hunter-gatherer and pastoralist groups that they encountered.
The Kalenjin are a group of tribes designated as Highland Nilotes and are descended from Maliri people (thus related to Daasanach of Ethiopia.) The Kalenjin are cousins with Datooga people of Tanzania and Malawi. In contrast, their designation groups them with other Nilotes including Maasai, Luo, Turkana and Nuer, Dinka among others. They are indigenous to East Africa, residing mainly in what was formerly the Rift Valley Province in Kenya and Eastern slopes of Mount Elgon in Uganda. Upon their arrival in the forest region of Mau, the Kalenjin assimilated the aboriginal hunter-gatherer people known as Okiek. They number 6,358,113 individuals as per the Kenyan 2019 census and an estimated 300,000 in Uganda mainly in Kapchorwa, Kween and Bukwo districts. They have been divided into 11 culturally and linguistically related tribes: Kipsigis, Nandi (937,000), Sebei Keiyo, Marakwet, Sabaot (296,000), Pokots, Tugen, Terik, Sengwer, and Ogiek. The Kalenjin speak the Nadi-Marakweta languages but can also be inclusive of Akie language in Tanzania and Pokot language spoken in Kenya; all being classified collectively as Kalenjin Language; while in combination with Datooga languages of Tanzania, this cluster is called Southern Nilotic languages.
The Abagusii are a highly diverse East African 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. The Abagusii are unrelated to the Kisi people of Malawi and the Kissi people of West Africa, other than the three communities having similar sounding names.
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.
The Afroasiatic Urheimat 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. This speech area is known as the Urheimat. Afroasiatic languages are today 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, or Bantu, are an ethnolinguistic grouping of approximately 400 distinct ethnic groups who speak Bantu languages. They are native to 24 countries spread over a vast area from Central Africa to Southeast Africa and into Southern Africa. There are several hundred Bantu languages. Depending on the definition of "language" or "dialect", it is estimated that there are between 440 and 680 distinct languages. The total number of speakers is in the hundreds of millions, ranging at roughly 350 million in the mid-2010s. About 60 million speakers (2015), divided into some 200 ethnic or tribal groups, are found in the Democratic Republic of the Congo alone.
Kaskazi is a name used to refer to an ancient ethno-linguistic group of Bantu peoples which took shape in the Western Rift area in the early centuries of the last millennium BC within the Mashariki group. The name comes from the swahili word for "northern wind", in opposition to the Kusi subgroup. The Kaskazi subgroup settled north of Mozambique and Malawi, while the Kusi settled in the south. Both the Kaskazi and Kusi did not form as single communities with a single language, but as clusters of communities speaking a variety of slightly different languages.
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.
Ancient Semitic-speaking peoples or Proto-Semitic people were people who lived throughout the ancient Near East, including the Levant, Mesopotamia, the Arabian Peninsula, and the Horn of Africa from the 3rd millennium BC until the end of antiquity.
