The acquisition of southern Bantu languages has been relatively well studied, with dissertations on the acquisition of the Sotho languages Sesotho (Connelly 1984, Demuth 1984) and Setswana (Tsonope 1987), and the Nguni languages Siswati (Kunene 1979) and Zulu (Suzman 1991), as well as a number of other articles on Sesotho and Zulu acquisition.

In particular, children learning southern Bantu languages have mastered the noun class and agreement system before the age of 3, and the competence with complex grammatical constructions and the grammatical tone system is
