Questions & Answers about Broj je na obrascu.
Because na here means on in the sense of location, and with that meaning it requires the locative case.
- dictionary form: obrazac = form
- locative singular: na obrascu = on the form
So:
- obrazac = the basic form of the noun
- na obrascu = after the preposition na when talking about where something is
This is a very common pattern in Serbian:
- na stolu = on the table
- na papiru = on the paper
- na obrascu = on the form
Obrascu is in the locative singular.
The noun obrazac is masculine, and after na expressing location, it changes to the locative:
- nominative: obrazac
- locative: na obrascu
In many Serbian grammar descriptions, na can take:
- locative for location: na obrascu = on the form
- accusative for movement toward something: na obrazac = onto the form / onto the document, depending on context
