Céad míle fáilte (a hundred thousand welcomes).
Pronounced (roughly) kayd MEE-luh FAHL-cheh
It's a common greeting or salute in Ireland.
On the street/in casual conversation, you're more likely to hear
Dia duit 'Hello' (literally 'God to you') and the response,
Dia 's Muire duit (literally 'God and Mary to you').
If you're addressing a group of people, it would be
Dia daoibh since Irish has a separation between the singular and plural 'you' forms, like French's
tu and
vous.
Here's the IPA for
Dia duit broken down by dialect region:
/dʲia dˠitʲ/ - Ulster (Gweedore) (very roughly approximated to
jee-ah ditch)
/dʲiə ɣitʲ/ - Connacht (Connemara) & Munster (Dingle) (
jee-uh ghwitch)
This is close as I can get without IPA since the /ɣ/ sound isn't really found in English.
(
https://en.wiktionary.org/wiki/%C9%A3 This does a better job of explaining this sound than I can.)
NOTE: In the Connacht and Munster dialects, it is possible for it to be written as
dhuit and
dhaoibh due to the final letter before it being a vowel. I believe both
duit and
dhuit are accepted by the Official written standard, but it's been a while since I checked so don't quote me on that.

Even these greetings are very slowly being phased out by the younger crowds in favor of things like Haigh
