This study is a creative and Relevance Theoretic reading of Achebe’s Things Fall Apart and Adichie’s Half of a Yellow Sun. Language as a complex phenomenon allows for a measure of innovation and creativity and that is why even with its limited resources, man can create limitless words and sequence of words to represent the ideas, thoughts, imaginations and relationships he intends. There have been many studies on the two works touching on different areas, published and unpublished, but very little has been done on the study of their creative import and its relevance in projecting the African impulse. The study aimed to examine how the old and new generations of African writers use the English language to express their African sensibilities without compromising the communicative competence required for effective projection of the intended message. The work provides a pragmatic platform for understanding the culture, traditions and reasons accounting for the linguistic manipulation as encountered in the texts, and also examines how linguistic creativity has been employed by Achebe in Things Fall Apart and Adichie in Half of a Yellow Sun as a design to achieve special contextual strengthening of the events and characterizations using the Relevance Theoretic Model. The study adopted the descriptive research design to analyze the language used by the writers. In the analysis, issues of context, implicature and relevance were applied. Furthermore, the study shows that pragmatics and socio-linguistics are important concepts for the understanding of messages as intended by the writer. The research shows that there are words, circumstances and situations a reader might not fully connect with or understand, unless he shares the same environment with the writer. It concludes that Achebe and Adichie have produced works that will continue to be relevant in literature for a long time.
