Pretoria Tswana, or Pretoria Sotho (affectionately called Sepitori by its speakers), is the urban lingua franca of Pretoria and the Tshwane metropolitan area in South Africa. It is a combination of Tswana and influences from Tsotsitaal, Afrikaans and other Bantu languages of the region. It is spoken by most black residents of all ages and levels of education in Tshwane. Though it is most commonly used in informal situations, it is also used in schools and at political events in which people have different language backgrounds. Standard Setswana and Northern Sotho (represented by Sepedi) are not commonly used in schools except in SeTswana and Northern Sotho lessons. Pretoria Tswana (or Sepitori) is mutually intelligible with SeTswana and Northern Sotho.
