Shakespeare made up words, yes, but he was a genius. No one is talking about rejecting words made up by any genius, either now or in the past. It's about not letting the "feccia del popolazzo" to influence proper English.

My point about the Greek roots is that the English language has the proper terms and they're being ignored by morons. Language should evolve, not devolve, which is what you're effectively arguing for.

Do I have a problem if Tolkien decided to coin the phrase "eucatastrophe"? No. Do I want to recognize slang terms that the Kardashians or Lizzo might choose to come up with? Hell no. Standards. You have to have some standards, damn it!
