Irish English, also termed 'Anglo-Irish' or 'Hiberno-English', as in this book, is not usually perceived as having a grammatical system of its own. Markku Filppula here challenges this misconception and offers a descriptive and contact-linguistic account of the grammar of Hiberno-English. Drawing on a wide range of authentic materials documenting Hiberno-English dialects past and present Filppula examines: the most distinctive grammatical features of these dialects relationships with earlier and other regional varieties of English the continuing influence of the Irish language on Hiberno-English similarities between Hiberno-English and other Celtic-influenced varieties of English spoken in Scotland and Wales. The Grammar of Irish English is a comprehensive empirical study which will be an essential reference for scholars of Hiberno-English and of value to all those working in the field of Germanic linguistics.
