"Nie możesz mieć małpy!"

Translation: You cannot have a monkey!

[Euhan1]

Can't you have a pet slug instead...

[PierreMDL]

HAHA ! So wait, I learned that the accusative object of a verb takes the genitive form if the verb is negated. But here it's even trickier because the modal verb is negated, and not the infinitive, which governs the accusative. But still the accusative has to turn into the genitive. Madness is upon our heads.

Polish is screwing with us...

What's the plural for monkey?

[Emwue]

Plural of „małpa” is „małpy”, which becomes „małp” in genitive – „Nie możesz mieć małp” = 'You can't have monkeys'.

Why do you correct me? (You can`t have a monkey)

[Jellei]

This should have worked.
