For American English speakers, the word “ceilidh” is probably a pronunciation puzzle. As it comes from Old Irish, the pronunciation rules are very different, but the correct way to say the word for a raucously fun party with singing, dancing, and storytelling is “KAY-lee.” The word is traced from the Scottish Gaelic “ceilidh” and the Irish “célidhe,” back to the Old Irish word “céilide,” which means “visit,” and “céile,” which means “companion.”
