History

　　Origin of name

　　The word Halloween is first attested in the 16th century and represents a Scottish variant of the fuller All-Hallows-Even ("evening").

　　Symbols

　　Development of artifacts and symbols associated with Halloween formed over time. For instance, the carving of jack-o'-lanterns springs from the souling custom of carving turnips into lanterns as a way of remembering the souls held in purgatory. The turnip has traditionally been used in Ireland and Scotland at Halloween,but immigrants to North America used the native pumpkin, which are both readily available and much larger – making them easier to carve than turnips.The American tradition of carving pumpkins is recorded in 1837 and was originally associated with harvest time in general, not becoming specifically associated with Halloween until the mid-to-late 19th century

　　The imagery of Halloween is derived from many sources, including national customs, works of Gothic and horror literature (such as the novels Frankenstein and Dracula), and classic horror films (such as Frankenstein and The Mummy).Among the earliest works on the subject of Halloween is from Scottish poet John Mayne in 1780, who made note of pranks at Halloween; "What fearfu' pranks ensue!", as well as the supernatural associated with the night, "Bogies" (ghosts), influencing Robert Burns' Halloween 1785.Elements of the autumn season, such as pumpkins, corn husks, and scarecrows, are also prevalent. Homes are often decorated with these types of symbols around Halloween.

　　Halloween imagery includes themes of death, evil, the occult, or mythical monsters.Black and orange are the holiday's traditional colors.

　　Trick-or-treating and guising

　　Trick-or-treating is a customary celebration for children on Halloween. Children go in costume from house to house, asking for treats such as candy or sometimes money, with the question, "Trick or treat?" The word "trick" refers to a (mostly idle) "threat" to perform mischief on the homeowners or their property if no treat is given. In some parts of Scotland children still go guising. In this custom the child performs some sort of trick, i.e. sings a song or tells a ghost story, to earn their treats.

　　Foods

　　Because the holiday comes in the wake of the annual apple harvest, candy apples (known as toffee apples outside North America), caramel or taffy apples are common Halloween treats made by rolling whole apples in a sticky sugar syrup, sometimes followed by rolling them in nuts.

　　At one time, candy apples were commonly given to children, but the practice rapidly waned in the wake of widespread rumors that some individuals were embedding items like pins and razor blades in the apples.[33] While there is evidence of such incidents,[34] they are quite rare and have never resulted in serious injury. Nonetheless, many parents assumed that such heinous practices were rampant because of the mass media. At the peak of the hysteria, some hospitals offered free X-rays of children's Halloween hauls in order to find evidence of tampering. Virtually all of the few known candy poisoning incidents involved parents who poisoned their own children's candy.
