Breakdown of Moj sin želi nacrtati sovu koja sjedi iznad vrata štale.
Questions & Answers about Moj sin želi nacrtati sovu koja sjedi iznad vrata štale.
Because sovu is the accusative singular form, and it is the direct object of nacrtati.
- sova = an owl (dictionary form, nominative)
- sovu = an owl (as the object)
In this sentence, the son wants to draw the owl, so owl is what the action is done to.
- Moj sin želi nacrtati sovu = My son wants to draw an owl
This is very common in Croatian: the noun changes form depending on its role in the sentence.
Because koja is the subject of the relative clause.
The relative clause is:
- koja sjedi iznad vrata štale = which is sitting above the barn door
Here, the owl is the one doing the sitting, so the relative pronoun must be in the nominative:
- koja = which / who (feminine singular nominative)
If the owl were the object inside that clause, you would expect koju instead.
So the structure is:
- sovu = object of nacrtati
- koja = subject of sjedi
Even though both refer to the same owl, they belong to different parts of the sentence and therefore can have different cases.
