Abstract: Language and communication are inextricably interwoven. The crisscross nature of the duo is that each is given form and effect by the other. Language is expressed through communication and communication uses language to establish meaning. However, for a language to thrive in perpetuity, it requires the maintenance of a sizeable number of competent native speakers. This study investigated the fate of Nigerian minority languages in the face of rising inter-ethnic marriages. Among other objectives, the study investigated how inter-ethnic couples solve their language differences and the consequence of language divide among inter-ethnic couples on Nigerian minority languages. The survey research design was used to study a population of 483,379 from which a sample size of 384 was drawn. The study found that the major lingua franca adopted by inter-ethnic couples were English language and Nigerian pidgin. It was also found out that children born into inter-ethnic homes were constrained to acquire the lingua franca adopted by their parents as mother tongue. The study, recommended, among other things, that inter-ethnic couples should endeavour to learn the native languages of their spouses in order to save such languages from endangerment and sudden disappearance.
