Morphological Structures And Classification Of Neologisms In Ngugi Wa Thiong’o’s Murogi Wa Kagogo.

New technological advancements and innovations are a challenge to languages and especially so to African languages. New terminologies referred to as neologism thus become necessary. This research looks at the morphological structures and classification of neologisms in the Gĩkǔyǔ language. The study will show how innovatively languages deal with new terms and refute the argumentation that African languages are not developed enough to cater for these concepts. The study has focused its analysis on selected excerpts from Ngugi wa Thiong‟o since he is well published and many of his literary texts are available in Gĩkǔyǔ as well as English and Kiswahili. The themes in his texts also cut across diverse times, ranging from the pre-colonial, colonial and post-colonial eras. The study has narrowed down to his novel, Murogi wa Kagogo(2004) as it contains some of the most recent neologisms. The study identified and categorised the neologisms introduced in a Gĩkǔyǔ text. The study also analysed the morphological structures of the neologisms. The study has also evaluated the Gikuyu speakers‟ knowledge of these neologisms. This study is guided by Katamba‟s (1993) theory of open-endedness of the lexicon. It adopted a non-experimental research design and opted for purposive sampling. It majorly dealt with qualitative data hence took a qualitative data analysis approach. The study identified 249 neologisms, classified them in their respective grammatical (nouns, verbs, adjectives, adverbs) and semantic fields (technology, education, politics, geographical terms, religion), identified various morphological structures (affixation, modification, vowel change) and finally evaluated the Gikuyu speakers‟ knowledge of the neologisms. Tables and excerpts have been used in data presentation. The quantitative data analysis was also incorporated; hence, some numeric presentations have been made.
