The Sotho language (/ˈsuːtuː/; also known as Sesotho, Southern Sotho, or Southern Sesotho) is a Southern Bantu language of the Sotho-Tswana (S.30) group, spoken primarily in South Africa, where it is one of the 11 official languages, and in Lesotho, where it is the national language. Like all Bantu languages, Sesotho is an agglutinative language, which uses numerous affixes and derivational and inflexional rules to build complete words.
