The tone of Lord of the Rings changes significantly when you learn that Sauron isn’t his name but an elvish pun on it that basically means “that mother fucker”
especially when you learn that he kept calling himself smth like “Mairon the Admirable” or “Tar-Mairon” (King Excellent), despite all the Middle-Earth calling him “Stinky” (elv. saura - “foul, evil-smelling, putrid” ).
