 It's especially confusing because the meanings of "bringer" and "harbinger" are both "bearer of ____"

Sort of; a bringer would be someone who is actually *bringing* the thing. 

A harbinger is technically more of an *announcer* of the thing, or a sign of a thing, though in modern day these have started to be used interchangeably.

Yeah, exactly. I just figured the "har" part meant "news" or something in Old English or whatever. So the News Bringer or the Anouncement Bringer
