At least thirty-five languages are spoken in South Africa, twelve of which are official languages of South Africa: Ndebele, Pedi, Sotho, South African Sign Language, Swazi, Tsonga, Tswana, Venda, Afrikaans, Xhosa, Zulu and English, which is the primary language used in parliamentary and state discourse, though all official languages are equal in legal status. In addition, South African Sign Language was recognised as the twelfth official language of South Africa by the National Assembly on 3 May 2023. Unofficial languages are protected under the Constitution of South Africa, though few are mentioned by any name.
