Mompoloki Mmangaka Bagwasi is Professor and Head of Department of English at the University of Botswana where she has been teaching for more than three decades. She obtained her PhD from Indiana University, USA, in 2002. Her dissertation, “A Historical Development of a Botswana Variety of English”, is a sociolinguistic analysis of letters written by British administrators and Batswana chiefs between 1885 and 1966 when Bechuanaland (now Botswana) was a British protectorate. Most of her publications on Botswana English and critical discourse analysis are inspired by or based on data from the huge corpus of colonial correspondences she put together. Among her notable publications are “Education, multilingualism and bilingualism in Botswana” (International Journal of the Sociology of Language 267-268: 43-54 2021), “Englishising African cultures: Revisiting acculturated forms of English in Botswana” (Language, Culture and Curriculum, 27 (2): 196-208, 2014), and “Pragmatics of letter writing in Setswana” (Journal of Pragmatics 40 (3): 525-536, 2008).
