Abstract: Understanding how code-switching and code-mixing intersect withcharacter definition and identity may not be easily overlooked in a multidisciplinarystudy of this nature. Code-switching and code-mixing are usually common inmultilingual societies. The importance of these linguistic activities, particularly incommunication, calls attention to the need for more research into their occurrences.Communication is inevitable in building strong human relationships. In the study ofcharacter definition and identity, through the lens of code-switching and codemixing, pertinent intriguing questions to ask bother on how language use shapes therepresentation of characters, their relationships with others, and their self-perceptionwithin various contexts. The objectives of this study are to investigate the social andcultural implications of code-switching on character identity and explore thenarrator's identification through the same style in selected texts. To tackle the setobjectives of this study, the scholars followed the qualitative technique of contentanalysis in the study of the selected literary texts. There was intense observation ofsome library and internet print materials. The theoretical framework of the study isdrawn mainly from the views of the Accommodation theory of Code-switching andcode-mixing. The study discovers that the act of code-switching/code-mixing couldaid in the identification and revelation of the social, cultural and personal traits ofcharacters in a text. The same language act could also be a means of capturing anddefining the narrator of the text. It is recommended that African writers writing intheir lingua franca adopt the use of this device in projecting their cultural values,identity, ethics and language to a wider readership and accessibility.
