"We have your newspaper."

Translation: Mamy waszą gazetę.

[immerweiter]

why don't you not use here genitve

[immery]

there is always accusative after "mamy"
genitive is after negative - "nie mamy"

[immerweiter]

dziękuję bardzo

Why wouldn't Mamy twojej gazetę also be correct for singular you?

[Jellei]

'twojej' is Genitive. You need Accusative here: Mamy twoją gazetę.

[EdwardKeat3]

Dziekuję! That's very helpful.

Where can I find a table of the declensions for 'gazeta' ? I have looked but cannot find them.
