Questions & Answers about Na szczęście w torbie leży oryginał i jedna kopia.
Na szczęście is a fixed expression meaning fortunately or luckily.
Even though na often means on, you should treat na szczęście as one whole phrase. It is not understood word-for-word in normal speech.
So:
- Na szczęście = Fortunately / Luckily
Because w means in here, and when Polish uses w for a static location, the noun usually goes into the locative case.
The base form is:
- torba = bag
After w for location:
- w torbie = in the bag
So the ending changes because of case:
- torba → torbie
