The Bantu languages (English: UK, US Proto-Bantu: *bantʊ̀) are a language family of about 600 languages that are spoken by the Bantu peoples of Central, Southern, Eastern and Southeast Africa. They form the largest branch of the Southern Bantoid languages.
The total number of Bantu languages is estimated at between 440 and 680 distinct languages, depending on the definition of "language" versus "dialect". Many Bantu languages borrow words from each other, and some are mutually intelligible.
The total number of Bantu speakers is estimated to be around 350 million in 2015 (roughly 30% of the population of Africa or 5% of the world population). Bantu languages are largely spoken southeast of Cameroon, and throughout Central, Southern, Eastern, and Southeast Africa. About one-sixth of Bantu speakers, and one-third of Bantu languages, are found in the Democratic Republic of the Congo.
The most widely spoken Bantu language by number of speakers is Swahili, with 16 million native speakers and 80 million L2 speakers (2015). Most native speakers of Swahili live in Tanzania, where it is a national language, while as a second language it is taught as a mandatory subject in many schools in East Africa, and is a lingua franca of the East African Community.
Other major Bantu languages include Lingala with more than 20 millions speakers ( Congo, DRC), Zulu with 12 million speakers ( South Africa), Xhosa with 8.2 million speakers ( South Africa and Zimbabwe), and Shona with less than 10 million speakers (if Manyika and Ndau are included), while Sotho-Tswana languages (Sotho, Tswana and Pedi) have more than 15 million speakers (across, Botswana, Lesotho, South Africa, and Zambia). Zimbabwe has Kalanga, Matebele, Nambiya, and Xhosa speakers. Ethnologue separates the largely mutually intelligible Kinyarwanda and Kirundi, which together have 20 million speakers.
The similarity among dispersed Bantu languages had been observed as early as the 17th century. The term Bantu as a name for the group was coined (as Bâ-ntu) by Wilhelm Bleek in 1857 or 1858, and popularized in his Comparative Grammar of 1862.
