Jack-o'-lantern
Carved pumpkin or root vegetable lantern
A jack-o'-lantern (or jack o'lantern) is a carved lantern, most commonly made from a pumpkin, or formerly a root vegetable such as a mangelwurzel, rutabaga or turnip. Jack-o'-lanterns are associated with the Halloween holiday. Its name comes from the phenomenon of strange lights flickering over peat bogs, called jack-o'-lanterns (also known as will-o'-the-wisps).
