Do we say "Guess wrong?"

Is Guess wrong. correct in grammar?
Or we say You are wrong. when someone guess something wrong.
Thanks.

When someone guesses something wrong, you can tell them "You are wrong." You cannot say "Guess wrong."

I agree in the context of the poorly-phrased question. But "guess wrong" is a common phrasal verb in other contexts.

E.g., You'd better guess right, because if you guess wrong you are dead.

So "guess wrong" is certainly grammatically correct.

You can say 'Wrong guess', meaning '(That's a) wrong guess' in the same way that a waiter in a restaurant often says 'Good choice' when you order a dish he likes, or 'Bad idea' when a friend suggests an inadvisable course of action.

It's not correct, but the reason is not because the grammar is wrong. Something can be grammatically correct but not correct usage.

How about 'You guessed wrong'?

 

[Tdol]

That's OK.

Thank you.

How about "You guessed wrongly"?

You guessed wrongly is grammatically correct but unnatural.
