This is a question that was brought up, so I thought I'd ask...?

Question

If "con" is the opposite of "pro", is "Congress" the opposite of "progress"?

Answer 1

I've heard that question many times and its still funny. But if you're serious, then I assume that congress is one word without a prefix.

Answer 2

good question. but as someone else said Congress may be a word without a prefix

Answer 3

If that's the way you want to look at it, then couldn't you say that congress is the opposite of aGRESSion?
