My go-to example is "awful". The original meaning is literally to be full of awe. I think you would be hard-pressed to find a speaker today that adheres to that meaning over simply meaning "very bad", which is almost an antonym.

Languages change and are influenced by their use, so you need to pick your battles. If something can be unambiguously understood then you're going to be fighting an uphill battle and it's only a matter of time
