ABSTRACT: The aim of this paper was to describe the way in which the emphasis on Swahili has affected secondary education in Tanzania, and this has attracted many scholars within and outside Africa. The Ludwig Wittgenstein theoretical framework of picture and language games was used to indicate that the limits of my language are the limits of my world‟. The paper is a descriptive in nature and it intends to describe the way the emphasis of Swahili has affected Tanzania on education. The paper shows that approach to linguistics used in the past has prevailed without change. This has led to language problems and setbacks for the majority of Tanzanians when it comes to international job market. English language as the medium of instruction in the country has been the victim, as blamed by many scholars within and outside Tanzania as the cause of poor performance in secondary schools. However, the study has revealed that Swahili has played a significant role as a unifying factor among the Tanzanians and has helped to solve the issue of tribalism.
