Questions & Answers about Bicikl je ukraden.
Croatian does not have articles, so there is no direct equivalent of the or a/an in normal sentences.
So bicikl can mean:
- a bicycle
- the bicycle
Which one is meant depends on context.
In Bicikl je ukraden, the context usually makes it clear whether you mean the bicycle or just a bicycle.
Bicikl is in the nominative singular.
That is because it is the subject of the sentence:
- Bicikl = the thing being talked about
- je ukraden = is/was stolen
The basic dictionary form is also bicikl, so in this sentence the nominative looks the same as the citation form.
