In multilingual societies such as Botswana, language use is an extremely complex matter, further compounded by the fact that the languages involved are themselves dynamic phenomena that often elude the planned outcomes of policies which try to shape and constrain them. The paper describes the functional distribution of the national language Setswana, spoken as a mother tongue by 80% of the population, and English, the official language in Botswana. The role of the two languages is outlined, with particular regard to cultural identity, on the one hand, and social and economic status on the other.
