n modern usage, a céilidh or ceilidh /ˈkeɪli/ is a traditional Gaelic social gathering, which usually involves playing Gaelic folk music and dancing. It originated in Scotland and Ireland and is consequently common in the Scottish and Irish diasporas, as well as throughout England where it has undergone 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]).
