You can say it as you've stated as English is the main language in Ireland. There is also an Irish language and to say thank you in it you would say "Go raibh maith agat." This would be pronounced "G'rev ma agut."
"Go raibh maith agat." (to one person)
"Go raibh milé maith agaibh." (to more than one person)
The same way you would anywhere else. They have a different accent, not a different language =P
Go raibh maith agat (gura moy ugut) may goodness be upon you literally but it's how you say thank you
Go raibh míle maith agat (singular)
Go raibh míle maith agaibh (plural)
Thank you is Go raibh maith agat and you is tu
Go raibh maith agat (agaibh, plural).
You're welcome = Tá fáilte romhat.
Irish Gaelic?
Go raibh maith agat as éisteacht
Thanks.
Merci avoir un bon jour no, that's French
You can say "Many thanks, my friends" to express gratitude to your friends.
You can use one of many parting remarks: Bye See-ya Tarra So Long Good Bye Many thanks Safe Home (more Irish) The best way to say goodbye is to say Cheerio!
In Irish it's "Go raibh maith agat as do chairdeas" Scottish:
Moladh le Dia. Buíochas le Dia (Thanks be to God)
Dialects in Ireland vary by region, but many Irish people do say "mate" as a slang term for friend.
