Book excerpt: This volume offers a comprehensive overview of the range of varieties of English spoken on the island of Ireland, featuring information on their historical background, structural features, and sociolinguistic considerations. The first part of the volume explores English and Irish in their historical framework as well as current issues of contact and bilingualism. Chapters in Part II and Part III investigate the structures and use of Irish English today, from pronunciation and grammar to discourse-pragmatic markers and politeness strategies, alongside studies of specific varieties such as Urban English in Northern Ireland and the Irish English spoken in Dublin, Galway, and Cork. Part IV focuses on the Irish diaspora, with chapters covering topics including Newfoundland Irish English and Irish influence on Australian English, while the final part looks at the wider context, such as the language of Irish Travellers and Irish Sign Language. The handbook also features a detailed glossary of key terms, and will be of interest to a wide range of readers interested in varieties of English, Irish studies, sociolinguistics, and social and cultural history.
