Questions & Answers about Bez ugovora najam nije moguć.

Why is bez followed by ugovora and not ugovor?

Because bez (without) is a preposition that requires the genitive case in Croatian.
So ugovor (contract) changes to the genitive singular ugovora after bez: bez ugovora = without a contract.

How do I know ugovora is genitive singular and not something else?

The noun ugovor is masculine, and its genitive singular ending is typically -a:

• nominative: ugovor
• genitive singular: ugovora
  Also, the meaning fits: without a (single) contract. (Genitive plural would usually be different in meaning and often in form, depending on the noun.)

What part of speech is najam here, and what does it function as in the sentence?

Najam is a noun meaning rental / renting / lease (depending on context).
Here it is the subject of the sentence (in the nominative case): Najam nije moguć = Renting is not possible.
