This study looks at the morphological restructuring of Swahili words to a new emerging Sheng in Nakuru Town. The study looks at the speech repertoire of matatu crew and their interlocutors and analyzes how in-group and out-group correlate with the new emerging Sheng. It is difficult to follow a conversation in the emerging Sheng and thus it is against this background that an attempt will be made to unravel the new formations in the emerging Sheng and the changes they
undertake morphologically. The study will thus look at the processes involved in changing the words from Swahili to the emerging Sheng The theoretical framework for this study will consist of Speech Accommodation Theory as explained by Coupland and Giles (1991) and The Lexical and Word Based Morphological Theories as propounded by Bauer (1983). Research instruments used for data collection include unstructured interviews, tape recording and
observation notes.The data will be analyzed both qualitatively and quantitatively.
