What does Cead Mile Failte mean?

Answer:

Answer

The phrase appears in both Irish and Scottish Gaelic.
In both, it means "A Hundred Thousand Welcomes".

In Irish, it's spelled Céad Míle Fáilte. In Gaelic (Scottish), Ceud Mìle Fàilte.

That's fine for a sign in a pub or shop. But to be grammatically correct, if you're saying it to a person, it should be "A hundred thousand welcomes to you" :

Céad míle fáilte romhat (Irish) or Ceud mìle fàilte dhut (Scots Gaelic).

It's pronounced kayd meeluh foll-tjuh roe-uht in Irish,

and kee-ud meel-uh faahl-tjuh gooht in Gaelic.
