Did you know there are six Celtic languages, one of which is called Manx? That one I had to look up! (the Isle of Man).
Breton, Cornish, Irish, Manx, Scottish, Gaelic, Welsh
I’ve learned to say two useful things today from Omniglot:
Dia dhuit (sg) Hello ( Good day)
Céad míle fáilte (hundred thousand welcomes)
With my Latin from 8th grade, some of the words look familiar- dia (day) dhuit (pronounced like “goot”). Also Cead ( ka-ah) resembles “cent” in French, mile (meel) like the French mile (thousand) and failte (foe- t)- essentially unfamiliar to me.
