Text in English / This dissertation, deals with the verb structure found in Ju/̕hoansi, Naro and !Xóõ, which form part of the Northern, Central and Southern Khoesan respectively. Although previous studies have been conducted on these languages, no study has been done to date involving a detailed comparison of the structures in these languages. Thus, not much has been done in the area of syntax; particularly syntactical comparison. Previous studies ignored comparisons of grammatical categories and structures such as noun class markers, plural formation markers, tense and aspect markers and verbal extensions. This dissertation consists of six chapters. Chapter 1 covers the language situation in Botswana. Chapter 2 is devoted to the literature review. Chapter 3 deals with the linguistic features found in the three languages. Chapter 4 covers the methodology and the theoretical framework adopted in the dissertation. The theoretical framework is eclectic in nature, in other words, the study is largely descriptive. However, on occasion, some aspects of lexical functional grammar (LFG) are used. This theoretical framework is appealing as it best handles important aspects of the languages under consideration, particularly the verb extensions. Chapter 5 describes the noun class system, highlighting the markers found in different noun classes. It also covers tense and aspect markers as well as the verbal extensions found in the three languages. Specifically, it is argued in this chapter that plural formation occurs in three ways; regular plurals, irregular plurals and neutral plurals. The study reveals a close relationship between tense and aspect and the motion of the events, points of reference and moment of speech encoded in the verbs involved. Adverbials can co-occur with the relevant tenses. Lastly, it is shown that verbal extensions do not just combine freely; they are subject to different kinds of sequential constraints. Chapter 6 summarizes the main findings, highlighting the similarities and differences in the three languages. Naro is SOV while Ju/'hoansi and !Xóõ are SVO. Chapter 6 also indicates areas in these Khoesan Languages requiring further research. / African Languages / D. Litt. et Phil. (African Languages)
