The study of English in Ireland has long had the origin of features of Irish English as one of its main themes. This is true both of the study of Irish English in general and Northern Irish English in particular. This interest is understandable, since the kind of contact language situation that Ireland, north and south has experienced has parallels throughout the postcolonial English-speaking world. The complex processes of interaction between Irish, Scottish, and English linguistic input have resulted in a rich cluster of dialect and accent features. This study deals with the English spoken in south-west Tyrone and the traces of the Irish language that are found in the language and language use of this area.
