"Ceilidh" is a Gaelic word that literally means "visit". In Gaelic speaking areas it often includes a house party with music, song, and storytelling. I suppose at times it may even include a dance in a barn
but "ceilidh" does not mean barn dance. An "English ceilidh" seems a strange term to Gaelic speakers but I guess the word is being absorbed into English with a changed meaning.
