African Language data provided by Wikipedia...
Following the end of colonialism, nearly all African countries adopted official languages that originated outside the continent, although several countries also granted legal recognition to indigenous languages (such as Swahili, Yoruba, Igbo and Hausa).
In numerous countries, English and French (see African French) are used for communication in the public sphere such as government, commerce, education and the media.
Arabic, Portuguese, Afrikaans and Spanish are examples of languages that trace their origin to outside of Africa, and that are used by millions of Africans today, both in the public and private spheres.
Italian is spoken by some in former Italian colonies in Africa. German is spoken in Namibia, as it was a former German protectorate.
