It is also spoken, and this, sparingly so, by Urhobo persons in the Diaspora. Presently, Urhobo has become a language of study at the Delta State University, Abraka. It has also been included in the educational curriculum for study at the lower cadre of secondary school education in the Delta State. This situation has triggered the author＇s interest in doing a contrastive phonological study. The significance of this study is that it will highlight the salient differences in some of the grammatical aspects in the languages under consideration and also identify the difficulties that learners experience as a result of these difficulties. The author will also, as much as it is possible, proffer solutions to these learning difficulties.展开更多
