Agreed. "Hallow" is an older synonym for "saint, holy person." So "Halloween" is the evening before All Saints' Day (November 1st).Even is a variant of Eve or Evening; you might compare the name of the Anglican equivalent of the Catholic service of Vespers: Evensong. Note, however, that it is "All Hallows", not "All Hallow."
Even was the noun for the end of the day (i.e. daylight.) Evening is a verbal noun meaning "the process becoming dusk; the sun setting." but is now seen as somewhere (very approximately) between 6pm and 9pm.Is it really Even or is it a typo?
Not so. The OED is clear on the etymology - a contraction of "All-Hallow-Even" - in its entry for "Hallow-e'en". "All-Hallow-Even" is included in the OED entry for "All-Hallows", which also has "All-Hallow-Eve", "All Hallows' Eve", "All Hallows' Even" and "All Hallown Eve".Note, however, that it is "All Hallows", not "All Hallow."
Just to be clear: "Halloween" is not a contraction in modern English. It is a normal word.Oxford's Advanced Learner's Dictionary says:
[Halloween] late 18th cent.: contraction of All Hallow Even
Is it really Even or is it a typo?
