This study examines the impact of multilingualism on the indigenous languages/dialects of Omuo people. The data for the study are obtained through the use of the questionnaires and interview. The theoretical framework adopted for the study is Domain of Language Behaviour. The study discovers that Omuo dialect, which is a subset of Ekiti dialect is distinguishable from all other Ekiti dialects most especially at the phonological level. The reason for this is accrued to the fact that Omuo shares boundary with two states- Kogi State and Ondo State as such dialects of the immigrants from these states have influenced Omuo dialect at the phonological and lexical level. This shows that multilingualism can lead to language variation, change and endangerment. Omuo people are therefore encouraged not to allow their language to be eroded or coloured through the influx of people to their community.
