Which case each preposition takes
You must learn which.
| Preposition | Case | Meaning |
|---|---|---|
| do | genitive | to, into |
| od | genitive | from |
| w | locative | in |
| na | loc (where) / acc (where to) | on, to |
| z | gen (from) / inst (with) | from / with |
| o | locative | about |
na/w + accusative (motion) vs locative (location).
Much of Polish case use is preposition-driven.
