There's no actual verb in Irish for 'to have'. Irish uses prepositional pronouns like 'agam/agat/aige/aici' to show that you have something, so to say "I have done something", you say "I am after doing it" in Irish, which transferred into Hiberno-English. In your example, there is no direct translation for "I have broken the cup" so it's "I'm after breaking the cup".

The word Ye. In my experience no place outside of ireland uses that word as a plural of you except newfoundland but that's basically Ireland anyways.

A good part of the population of Newfoundland can trace their ancestry back to the South East of Ireland. https://waterford.fyi/did-you-know-that-the-majority-of-irish-newfoundlanders-came-from-waterford-kilkenny-and-wexford/

In Irish, to scold somebody is "tabhair amach do", literally "give out to".

gowl is an interesting one. Used that word years ago in company and an old fella nearly had a heart attack. He whispered that it was a term for a woman’s private parts where he came from (East Cork) and considered very rude. Not sure if he was having me on, but he did seem quite shocked.
