Cèilidh
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, as well as throughout England in a fusion with English country dance. In Scottish Gaelic it is spelled cèilidh (Scottish Gaelic pronunciation: [ˈkʲʰeːli]), and in Irish it is spelled céilí (Irish pronunciation: [ˈceːlʲiː]).
Etymology
The term is derived from the Old Irish céle (singular) meaning "companion". It later became céilidhe and céilidh. In Scottish Gaelic reformed spelling it is spelled cèilidh (plural cèilidhean) and in Irish reformed spelling as céilí (plural céilithe).
History
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.
