Questions & Answers about Na dużej tablicy wiszą dwadzieścia liter z kolorowego papieru.
Because after na meaning on in a static location, Polish uses the locative case.
So:
- tablica = nominative, basic dictionary form
- na tablicy = on the board, locative
The adjective has to match the noun, so:
- duża tablica = a big board
- na dużej tablicy = on a big board
Both words change because Polish adjectives agree with the noun in case, gender, and number.
Because this sentence describes location, not movement.
- na dużej tablicy = on the big board → location, so locative
- na dużą tablicę = onto the big board → movement toward a surface, so accusative
A useful contrast:
- Litery wiszą na dużej tablicy. = The letters are hanging on the big board.
- Wieszam litery na dużą tablicę. = I am hanging the letters onto the big board.
So the key question is: Where? or Where to?
