Halloween is a contraction of All Hallows’ Evening, also known by Hallowe’en or All Hallow's Eve. This day was originally meant to honour the Saints and also pray for those recently departed and had yet to reach heaven.
Now most people just celebrate it as a time to dress up in scary costumes and go trick-or-treating.
If you mean this modern yank trick or treat thing, then commercialisation. If you mean Samain, it's just the end of the year, as measured by the Celts.
It is a pagen celebration.
It actually origiinated from Ireland in a town called Corchen (or soemthing, i forget)...It was because they had no religion and they were worshipig devils and ghosts and zombies ect...
So they decided to dress up as scary things to show support everyyear on the 31st of October.
Very silly!
I don't celebrate halloween...its for a very stupid cause. No benifit.
Because it's enjoyable, fun, and an opportunity to dress up in costumes. Which part of all that was confusing to you, and why are you asking this question in the 'words and wordplay' section?
