• As the foundation of homes, the marriage institution is an important agent of sociali- zation. In this regard, marriage can be relied upon as a major factor in language and cultural maintenance. However, mixed marriages may contribute to language shift in the home because they can lead to a change in language use patterns among minority language speakers and their children. This means that the likelihood of preserving a minority language is greater in marriages among individuals who speak the same indigenous language than in situations in which spouses speak different languages. This study uses questionnaire data from parents of ethnically mixed marriages to explain how mixed marriages contribute to language shift from minority languages to English (Nigeria's official language), Nigerian Pidgin (informal lingua franca) and the major languages (i.e. Hausa, Igbo and Yoruba) in the home domains. The study shows that the future of minority languages will largely depend on the roles of families and the value attached to minority ethnicAs the foundation of homes, the marriage institution is an important agent of sociali- zation.
