A jack-o'-lantern is a carved pumpkin, turnip, or other root vegetable lantern associated with Halloween. Its name comes from the phenomenon of a strange light flickering over peat bogs, called will-o'-the-wisp or jack-o'-lantern. The name is also tied to the Irish legend of Stingy Jack, a drunkard who bargains with Satan and is doomed to roam the Earth with only a hollowed turnip to light his way.
