The people of Ireland get annoyed with the fake Hollywood Irish accent and there’s a good reason for that: There are many different Irish accents, not just one.
Irish accents vary by counties, of course. People from Derry speak very differently from those in Roscommon, and people from Limerick don’t sound the same as the ones from Mayo. But even within these areas, there is an assortment of accents. In Ireland, you truly only need to drive 10 miles in any directions, and you’ll hear a different pronunciation of the English language.
