A jack-o'-lantern (or 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. Jack-o'-lanterns are a yearly Halloween tradition that came to the United States from Irish immigrants.In a jack-o'-lantern, the top of the pumpkin or turnip is cut off to form a lid, the inside flesh is scooped out, and an image—usually a scary or funny face—is carved out of the rind to expose the hollow interior. To create the lantern effect, a light source, traditionally a flame such as a candle or tea light, is placed within before the lid is closed. However, artificial jack-'o-lanterns with electric lights are also marketed. It is common to see jack-o'-lanterns on doorsteps, stoops and otherwise used as decorations prior to and on Halloween.
