An antiquarian is a person who studies or collects antiques or antiquities. But the prefix "anti" usually means "against" or "opposite of".
Why do I bring this up? Because in my mind if we have the word "antiquarian" we should also have the words "quarian" and "proquarian". But we don't and I needed to voice my disappointment.
And yes I am aware that the Quarians are a race of aliens from the game Mass Effect.
