Hello, I came across this word and according to wikipedia both spellings are correct. Anyone know which one is correct?
https://en.wikipedia.org/wiki/Holocaust_(sacrifice)
A holocaust is a religious animal sacrifice that is completely consumed by fire. The word derives from the Ancient Greek holokaustos (ὁλόκαυστος from ὅλος "whole" and καυστός "burnt", with rough breathing), which is used solely for one of the major forms of sacrifice. This form of sacrifice is also known as a burnt offering.
