In modern usage, a cèilidh or ceilidh is a traditional Gaelic social gathering, which usually involves playing Gaelic folk music and dancing. It originated from Ireland and Scotland, but is now common throughout the Scottish and Irish diasporas. In Scottish Gaelic it is spelled cèilidh, and in Irish it is spelled céilí. Originally, a ceilidh was a social gathering of any sort, and did not necessarily involve dancing. In more recent decades, the dancing portion of the event has usurped the older meanings of the term, though the tradition of guests performing music, song, story telling and poetry still persists in some areas.
