In the Republic of Ireland, English is one of two official languages, along with the Irish language, and is the country's de facto working language. Irish English's writing standards, such as its spelling, align with British English.[6] However, Irish English's diverse accents and some of its grammatical structures and vocabulary are unique, with some influences deriving from the Irish language and some notably conservative phonological features: features no longer common in the accents of England or North America. Phonologists today often divide Irish English into four or five overarching dialects or accents:[7][8] Ulster accents, West and South-West Irish accents (like the widely discussed Cork accent), various Dublin accents, and a non-regional standard accent expanding since only the last quarter of the twentieth century (outside of Northern Ireland).
