A jack-o’-lantern (sometimes also spelled Jack O’Lantern) is typically a carved pumpkin. It is associated chiefly with the holiday Halloween, and was named after the phenomenon of strange light flickering over peat bogs, called ignis fatuus or jack-o’-lantern. In a jack-o’-lantern, typically the top is cut off, and the inside flesh then scooped out; an image, usually a monstrous face, is carved onto the outside surface, and the lid replaced. At night a light (commonly a candle, although in recent years candles have fallen out of favor and are now considered unsafe because of the potential for fires) is placed inside to illuminate the effect. The term is not particularly common outside North America, although the practice of carving lanterns for Halloween is.
