The Afroasiatic languages are a language family of about 400 languages spoken predominantly in West Asia, North Africa, the Horn of Africa, and parts of the Sahara and Sahel. Over 500 million people are native speakers of an Afroasiatic language, constituting the fourth-largest language family after Indo-European, Sino-Tibetan, and Niger–Congo. Most linguists divide the family into six branches: Berber, Chadic, Cushitic, Egyptian, Omotic, and Semitic. The vast majority of Afroasiatic languages are considered indigenous to the African continent, including all those not belonging to the Semitic branch.
The Chadic languages form a branch of the Afroasiatic language family. They are spoken in parts of the Sahel. They include 196 languages spoken across northern Nigeria, southern Niger, southern Chad, and northern Cameroon. By far the most widely spoken Chadic language is Hausa, a lingua franca of much of inland Eastern West Africa, particularly Niger and the northern half of Nigeria. Hausa, along with Mafa and Karai Karai, are the only three Chadic languages with more than 1 million speakers.
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.
Niger–Congo is a hypothetical language family spoken over the majority of sub-Saharan Africa. It unites the Mande languages, the Atlantic–Congo languages, and possibly several smaller groups of languages that are difficult to classify. If valid, Niger–Congo would be the world's largest in terms of member languages, the third-largest in terms of speakers, and Africa's largest in terms of geographical area. Austronesian has almost as many member languages, although this is complicated by the ambiguity about what constitutes a distinct language; the number of named Niger–Congo languages listed by Ethnologue is 1,540.
The Nilo-Saharan languages are a proposed family of around 210 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.
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 many works, including Reconstructing Proto-Afrasian (1995) and Ancient Africa (2023). 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 Somali languages.
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.
The Nilotic languages are a group of related languages spoken across a wide area between South Sudan and Tanzania by the Nilotic peoples.
The Eastern Nilotic languages are one of the three primary branches of the Nilotic languages, themselves belonging to the Eastern Sudanic subfamily of Nilo-Saharan; they are believed to have begun to diverge about 3,000 years ago, and have spread southwards from an original home in Equatoria in South Sudan. They are spoken across a large area in East Africa, ranging from Equatoria to the highlands of Tanzania. Their speakers are mostly cattle herders living in semi-arid or arid plains.
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.
In most classifications, the Eastern Sudanic languages are a group of nine families of languages that may constitute a branch of the Nilo-Saharan language family. Eastern Sudanic languages are spoken from southern Egypt to northern Tanzania.
The Maa languages are a group of closely related Eastern Nilotic languages spoken in parts of Kenya and Tanzania by more than a million speakers. They are subdivided into North and South Maa. The Maa languages are related to the Lotuko languages spoken in South Sudan.
Proto-Afroasiatic (PAA), also known as Proto-Hamito-Semitic, Proto-Semito-Hamitic, and Proto-Afrasian, is the reconstructed proto-language from which all modern Afroasiatic languages are descended. Though estimations vary widely, it is believed by scholars to have been spoken as a single language around 12,000 to 18,000 years ago, that is, between 16,000 and 10,000 BC. Although no consensus exists as to the location of the Afroasiatic homeland, the putative homeland of Proto-Afroasiatic speakers, the majority of scholars agree that it was located within a region of West Asia or Northeast Africa.
The Aroid or Ari-Banna languages possibly belong to the Afro-Asiatic family and are spoken in Ethiopia.
Rendille is an Afro-Asiatic language spoken by the Rendille people inhabiting northern Kenya. It is part of the family's Cushitic branch.
Proto-Berber or Proto-Libyan is the reconstructed proto-language from which the modern Berber languages descend. Proto-Berber was an Afroasiatic language, and thus its descendant Berber languages are cousins to the Egyptian language, Cushitic languages, Semitic languages, Chadic languages, and the Omotic languages.
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 Western Asia and North Africa.
Ik is one of the Kuliak languages of northeastern Uganda. The Kuliak languages form their own branch of the proposed Nilo-Saharan language family. With the other two Kuliak languages being moribund, Ik may soon be the sole remaining language of its family.
Nyang'i (Nyangia) is the nearly extinct Kuliak language of the Nyangea hunter-gatherers of northeastern Uganda. The 15,000 Nyangia have shifted to speaking Karamojong.
Proto-Cushitic is the reconstructed proto-language common ancestor of the Cushitic language family. Its words and roots are not directly attested in any written works, but have been reconstructed through the comparative method, which finds regular similarities between languages not explained by coincidence or word-borrowing, and extrapolates ancient forms from these similarities.
