The Sotho-Tswana languages are a group of closely related Bantu languages spoken in Southern Africa.
The Sotho-Tswana group corresponds to the S.30 label in Guthrie's 1967–71 classification[1] of languages in the Bantu family.
On more than one occasion, proposals have been put forward to create a unified standardisation and declare a Sotho-Tswana language.
The group is divided into four main branches:[2] Northern Sotho, which appears largely to be a taxonomic holding category for what is Sotho-Tswana but neither identifiably Southern Sotho nor Tswana,[3] subsumes highly varied dialects including Pedi (Sepedi), Tswapo (Setswapo), Lovedu (Khilobedu), Pai and Pulana.
Maho (2002) leaves the "East Sotho" varieties of Kutswe, Pai, and Pulana unclassified within Sotho-Tswana.
