Etymology

The word Halloween or Hallowe'en (" Saints ' evening") is of Christian origin; a term equivalent to "All Hallows Eve" is attested in Old English. The word halloween comes from the Scottish form of All Hallows' Eve (the evening before All Hallows' Day): even is the Scots term for "eve" or "evening", and is contracted to e'en or een; (All) Hallow(s) E(v)en became Hallowe'en.
