South Africa, officially the Republic of South Africa, is a country located at the southern tip of Africa. It is divided into nine provinces and has 2,798 kilometres (1,739 mi) of coastline. To the north lie the neighbouring countries of Namibia, Botswana and Zimbabwe; to the east are Mozambique and Swaziland; while Lesotho is an enclave surrounded by South African territory. South Africa is the 25th largest country in the world by area and the 24th most populous country with over 48 million people. South Africa is a multi-ethnic nation and has diverse cultures and languages. Eleven official languages are recognised in the constitution. Two of these languages are of European origin: South African English and Afrikaans, a language which originated mainly from Dutch that is spoken by the majority of white and Coloured South Africans. Though English is commonly used in public and commercial life, it is only the fifth most-spoken home language.
