The study investigated language policy and planning in relation to minority languages and specifically Tshwao, a Khoisan language, in Zimbabwe. The purpose of the study was to establish its impact on the current sociolinguistic status of Tshwao. The ultimate goal was to suggest guidelines for the implementation of the Constitution of Zimbabwe (Amendment No. 20) Act, 2013 which officially recognised sixteen languages including ‘Koisan’ and to make recommendations for future language planning for endangered languages in general. The study is qualitative in nature. It used interviews, document analysis, observation and focus groups to gather data. Critical Discourse Analysis and Ethnolinguistic Vitality were the main theories which guided the study. The study showed that even though Tshwao is the Khoisan language that is popular, there are several other varieties such as Jitshwa, Xaise, Cirecire and Ganade and they are all endangered with very low demographic, status and institutional support. The Khoisan people have shifted to Ndebele and Kalanga, languages which are spoken by their neighbours. Both linguistic and extra-linguistic factors were shown in the study to have affected the maintenance of Khoisan languages. Numerical domination of the Khoisan by the Bantu people, subjugation by Mzilikazi during his conquests as well as selective development of languages by missionaries led to assimilation and language marginalisation. The implementation of discriminatory land, wildlife and language polices by the colonial government also resulted in relocations, language contact situations and dispersed settlements, all of which affected language maintenance. In the post-independence era, political instability, official and unofficial language policies were shown as having perpetuated the plight of Khoisan languages, including Tshwao. The constitution emerged as a milestone towards upholding minority languages. Its effectiveness is however compromised by inaccuracies and ambiguities in the manner in which provisions are crafted. The study concludes that Khoisan language endangerment spans from history. Formal and informal language policies contributed to the current state of endangerment. It further concludes that if effective revitalisation is to be done in line with implementing the constitution, all the factors which contributed to endangerment have to be taken into account. The study also suggests a separate guideline for the promotion of minority languages in general and displaced and endangered languages like Tshwao in particular. / Linguistics and Modern Languages / D.
