Why can't one say "Idź do domu"?
It means "Go home" (2nd person singular imperative).
Is the question about you go or you walk. It seems that you are confusing two usages
so, shouldn't [ty idziesz do domu] be possible, too, and if not, why not? :)
I want to ask the same thing. Why is this version wrong? Thats how I hear it from Polish speakers..
