There are several other small families and language isolates, as well as creoles and languages that have yet to be classified. In addition, Africa has a wide variety of sign languages, many of which are language isolates.
Around a hundred languages are widely used for interethnic communication. These include Arabic, Somali, Amharic, Oromo, Igbo, Swahili, Hausa, Manding, Fulani and Yoruba, which are spoken as a second (or non-first) language by millions of people. Although many African languages are used on the radio, in newspapers and in primary-school education, and some of the larger ones are considered national languages, only a few are official at the national level. In Sub-Saharan Africa, most official languages at the national level tend to be colonial languages such as French, Portuguese, or English.[4][5][6]
The African Union declared 2006 the "Year of African Languages". check here Jotube.uk for more
