The selected novel evokes important questions on the nature of language in Kenya during post-colonial era. It gives a truthful description of the implementation of the language among the social classes in Kenya. In this research, we are interested in the literary function of language and why the novelist chooses Gikuyu language as most expressive vernacular medium. This study offers a more adequate account of language’s figurative aspects, it clarifies the writer’s stylistic strategies and his use of techniques such as narrative suspense, proverbs, songs and figurative language to respond to the domination of the white oppressor in this era. The dissertation examines Ngugi wa Thiong’o Petals of Blood from both stylistic and thematic angles. The first chapter deals with the socio-historical context and theoritical background of the novel. It highlights Politics of Language and the events that surrounded the process of writing this literary piece. Also it provides general insights on Decolonizing the Mind. Hence, it sets out to deal with hypothetical thoughts embodied in the novel. Furthermore, in the second chapter, we examine ways in which Ngugi’s Petals of Blood is a motivated step for the African postcolonial writers to imply their mother tongue. We try also to explain the language persecution suggested by Ngugi when it comes to produce written words concerning the African literature; i.e. this part aims at inspecting and clarifying Ngugi’s stylistic strategies.enThesis
