I know. I know. It should be “nauseated”. I’ve never been so ashamed.
For those of you who don’t know, if something is “nauseous” then it causes queasiness. A smell is nauseous. If you are FEELING ill, then you are nauseated. Now YOU TOO can correct your peers with a feeling of smug superiority in your greater grammar! Strunk and White are the only friends I need!
