A Ceilidh (pronounced "Kay-lay", emphasis on 1st syllable) is many things. It derives from the Gaelic word meaning a visit and originally meant just that (and still does in Gaelic). It can also mean a house party, a concert or more usually an evening of informal Scottish traditional dancing to informal music. Ceilidhs in the Lowlands tend to be dances, in the Highlands they tend to be concerts. Dances in the Highlands and traditional ceilidhs in the Lowlands are often called "ceilidh dances". Ceilidh dancing is fundamentally different from Scottish Country Dancing in that it is much less formal and the primary purpose is the enjoyment of doing the dance.
