This article criticizes the language practices and language-in-education policy of Botswana from a translanguaging viewpoint. By so doing, it revisits commonly held perceptions about multilingualism, bilingualism and language and its boundary. We commonly perceive languages as autonomous and as having boundaries and we perceive bilingualism or multilingualism as consisting of two or more of these fixed languages. Such views have come under attack by theorists who, after observing the movements of people and languages as well as the language practices of bilinguals, have come to the conclusion that languages can neither be separated nor fixed to any one speech community, location or function. The current article finds weakness in Botswana’s approach to language planning and language-in-education policy. It asserts that the approach does not foster multilingualism, that it is out of touch, and prescriptive in so far as it fails to recognize that multilingualism is supposed to embrace flexibility, continuity and multiplicity. The article argues for the translanguaging approach which appreciates the fuzziness of language boundaries, the fluidity and creativity of languages instead of their distinctiveness. The article advises a language-in-education policy which is akin to what bilinguals do in their speech and conversations, that is, a language policy that allows for the use of several languages in the classroom and enables learners to employ their whole linguistic repertoire to interrogate issues, understand the subject matter and express themselves fully.
