Hiberno-English or Irish English (IrE), also formerly sometimes called Anglo-Irish, is the set of dialects of English native to the island of Ireland. In both the Republic of Ireland and Northern Ireland, English is the dominant first language in everyday use and, alongside the Irish language, one of two official languages (with Ulster Scots, in Northern Ireland, being yet another local language). Irish English's writing standards, such as its spelling, align with British English. However, Irish English's diverse accents and some of its grammatical structures and vocabulary are unique, including certain notably conservative phonological features and vocabulary: those that are no longer common in the dialects of England or North America. It shows significant influences from the Irish language and, in the north, the Scots language. Phonologists today often divide Irish English into four or five overarching dialects or accents: Ulster or Northern Irish accents, Western and Southern Irish accents (like Cork accents), various Dublin accents, and a non-regional standard accent (outside of Ulster) whose features have been developing since only the last quarter of the 20th century onwards.
