Negation and the genitive
Change many accusative direct objects to genitive after a negated verb.
Understand the choice
The negative genitive is one of Polish’s central case alternations. Learn pairs: mam kawę/nie mam kawy, jem mięso/nie jem mięsa, widzę Annę/nie widzę Anny.
Core rule: A direct object that would be accusative in an affirmative clause commonly takes genitive under verbal negation.
Notice it in context
Mam samochód, ale nie mam roweru.
I have a car, but I do not have a bicycle.
Samochód is positive accusative inanimate; roweru is genitive after nie mam.
Piję herbatę, ale nie piję kawy.
I drink tea but do not drink coffee.
Herbatę is accusative; kawy genitive under negation.
Ona widzi psa, ale nie widzi kota.
She sees the dog but not the cat.
Psa is animate accusative; kota is genitive negative object.
What to remember
- Some modern usage permits accusative in restricted contrasts, but genitive is the core learner pattern.
- Negating być does not create an object: to nie jest kawa.
Common trap: Do not leave the affirmative object form unchanged after ordinary verbal negation.
