A Comparative Study of Kiswahili Dialects: A Case of Standard Kiswahili, Kitumbatu and Kimakunduchi from a Historical Perspective

This study explores the three dialects of Kiswahili, including Standard Kiswahili, spoken throughout Tanzania, and

Kitumbatu and Kimakunduchi, spoken in Zanzibar, through a comparative linguistic analysis. The paper aims to examine the differences among the three dialects, addressing a gap in comparative research on their phonological, morphological, lexical, and syntactic features. Guided by the principles of historical linguistics and dialectology, the study applies a comparative method to selected phonological, morphological, lexical, and syntactic differences and similarities among the three dialects. This paper uses a qualitative comparative design and follows a synthetical approach. It combines field data collected directly from 12 L1 speakers with secondary data from the dictionaries of Kitumbatu and Kimakunduchi. Primary data were collected through semi-structured interviews, and guided elicitation. Verbal consent was sought from informants before data collection. The findings reveal that although all varieties share the same Bantu grammatical foundation, they differ in sound patterns, vocabulary, and morphosyntactic structures. Kitumbatu retains more conservative linguistic features, which may be associated with relative geographical isolation, while Kimakunduchi shows evidence of both internal development and external linguistic influences that make it more similar to Standard Kiswahili. Generally, dialectal variation in Zanzibar reflects broader historical and socio-cultural dynamics along the East African coast. By examining these three dialects comparatively, this research contributes to a deeper understanding of internal diversification within

Kiswahili and highlights the importance of documenting local dialects for both academic inquiry and cultural preservation, and the broader study of historical and comparative linguistics.
