Out of curiosity, are any of the following words and phrases actually used by Irish people? If not, then where did they actually originate?
"Top O' the Mornin' to Ya"
As far as I know, "wee" & "lassie" are Scottish not Irish. "Aye" is an older form which lingers on in some places/contexts (but, again, more of a Scottish thing, to my knowledge). I've heard or read that "top o' the morning to ya" is not an authentic Irish greeting.
For one reason or another, I had always assumed "top of the mornin' to ya" was an older English saying, like poppycock or something.
As far as I'm aware it's afake Irishism invented for some song or movie or something but I'm not sure.
"aye" is a common term used all over the British Isles.
We use it all the time in north-east England, however it is rarely used in the south of England.
I use aye from time to time, but it is something that I just picked up in the last few years.
It is common in the North of Ireland though.
