Halloween is a holiday celebrated each year on October 31. The tradition originated with the ancient Celtic festival, when people would light bonfires and wear costumes to ward off ghosts.
Origin of the word Halloween
The word Halloween or Hallowe’en has a origin dating back to 1745. Hallowe’en means Saints evening and “Hallow” by itself means saints. “Even” means Eve and hence it was later shortened to just “e’en” or “een”. So in time Hallow Even was changed to Hallowe’en and eventually to Halloween.
The custom of trick-or-treating on Halloween may come from the belief that supernatural beings, or the souls of the dead, roamed the earth at this time and needed to be appeased. It may otherwise have originated in a Celtic festival, held on 31 October–1 November, to mark the beginning of winter.
Why is the pumpkin a symbol of Halloween?
In Ireland, people started to carve demonic faces out of turnips to frighten away Jack's wandering soul. When Irish immigrants moved to the U.S., they began carving jack-o'-lanterns from pumpkins, as these were native to the region.
