The impact of the morphological alternation of subject markers on tense/aspect: the case of Swahili

Subject markers for the first, second and third person singular in Southern Swahili dialects display morphological variation in that specific forms are chosen with different tense-aspect markers. This paper documents this variation in the different dialects and presents a distributional chart which reveals the symmetric patterns between these subject markers and their corresponding tense-aspect formatives. The study corroborates earlier work in the manifestation of variant morphological tense-aspect formatives of the regional dialects of Swahili by Mazrui (1983)
