This is crazy. As I was trawling online etymology forums, I came across the peculiar history of Lucifer. In the beginning, there was nothing (haha), until the Romans went along and invented the word lux, meaning "light", with a conjugated form luc. The Romans built upon that word by tacking on the suffix -fer, meaning "bringing". So lucifer originally referred to "light-bringing", or as it came to be used, "morning star" or "light on the horizon". This Satanic word originally meant something good, completely opposite from its current definition. However, when people decided to make the Bible, the Lord says in Isaiah 14:12 "How you have fallen from heaven, lucifer, son of the dawn!" Thus, Lucifer became sort of a proper noun and came to refer to fallen angels. At that point, it was only a skip, a hop, and a jump until the ultimate transition was made from "corrupt angel" to "the ultimate opposing force against God", with Lucifer's present-day synonyms including very nasty words like "the Devil", "Satan", and "Beelzebub", which shouldn't be associated with "light-bringer", but sadly they are.
