Questions & Answers about Staza kroz šumu je uska.
Because kroz is a preposition that takes the accusative case.
- šuma = forest in the nominative form
- šumu = forest in the accusative singular
So:
- kroz šumu = through the forest
This is a very common pattern in Croatian: certain prepositions require a specific case, and kroz regularly goes with the accusative.
Staza is in the nominative singular because it is the subject of the sentence.
The sentence is about the path:
- Staza = the path
- je uska = is narrow
So staza is the thing being described, which is why it appears in the nominative.
