Tanzania is a unique country in sub-Saharan Africa in having a single, widely used and accepted African national language that connects its entire population. Kiswahili – a language estimated to have at least 100 million speakers across the continent is mostly spoken there; it is also the only official international language of Africa that is really indigenous to the continent. Tanzania boasts highest proficiency in the language, although there is a craze amongst the country’s population threatening to take that pride away.
