Koala, you might be right on that chcieć takes the genitive/dopełniacz, but I'm nost sure. Swan's "Grammar of Contemporary Polish" says
VERBS REQUIRING THE GENITIVE
d. Verbs of need, want, desire, demand:
- chcieć want
- ...
On the other hand, the examples I have in Rosetta Stone are inconsistent:
- Czy chcesz tortu? [genitive/dopełniacz]
- Dziewczynka chce czekoladę. [accusative/biernik]
- Czy chciałaby pani herbaty? [genitive/dopełniacz]
- Chciałabym soku pomarańczowego. [genitive/dopełniacz]
Can anybody clarify what's going on there?
That's an interesting wrinkle that some verbs take the genitive instead of the accusative. I'll have to build that into my little quiz program. What fun!
