By most estimates, Africa contains well over a thousand languages, some have estimated it to be over two thousand languages (most of African rather than European origin). Africa is the most polyglot continent in the world; it is not rare to find individuals there who fluently speak not only several African languages, but one or two European ones as well. There are four major language families native to Africa.
The Afro-Asiatic languages are a language family of about 240 languages and 285 million people widespread throughout East Africa, North Africa, the Sahel, and Southwest Asia.
The Nilo-Saharan language family consists of more than a hundred languages spoken by 30 million people. Nilo-Saharan languages are mainly spoken in Chad, Ethiopia, Kenya, Sudan, Uganda, and northern Tanzania.
The Niger-Congo language family covers much of Sub-Saharan Africa and is probably the largest language family in the world in terms of different languages. A substantial number of them are the Bantu languages spoken in much of sub-Saharan Africa.
The Khoisan languages number about 50 and are spoken in Southern Africa by approximately 120 000 people. Many of the Khoisan languages are endangered. The Khoi and San peoples are considered the original inhabitants of this part of Africa.
Following colonialism, nearly all African countries adopted official languages that originated outside the continent, although several countries nowadays also use various languages of native origin (such as Swahili) as their official language. In numerous countries, English and French are used for communication in the public sphere such as government, commerce, education and the media. Arabic, Portuguese, Afrikaans and Malagasy are other examples of originally non-African languages that are used by millions of Africans today, both in the public and private spheres.
