What is the case of 'psa' in this sentence? I'd assume it is genitive, am I wrong?
Must be genitive because of the negation
I wrote "Pan nie widzi psa?"
Is this wrong?
I think this meaning is just yet not included. It is 100% correct, but draws attention to "Pan". I would say "Nie widzi pan psa?" is more common sentence
Czy ty nie widze psa? Why is this wrong?
Ty (optional) widzisz (2nd sing.) => Ty (optional) nie widzisz (2nd sing. but negative)
Widzicie (2nd plur.) => Nie widzicie (2nd plur. negative)
