I learned one sentence recently.
He is anything but well.
Here "but" should be preposition and "well" be adjective. Right?
Is it common in English?
As I know, word after preposition is often noun, pronoun, etc, but not adjective.
Hi The French,
Thank you very much for your attention and response.
But what you said cannot explain another sentence that I learned along with the first one I mentioned above.
She is all but beautiful.
Have you ever met similar case?
