Agent in Passive Voice (s + Instrumental)
Grammar Rule in 30 Seconds
In Croatian passive sentences, the 'doer' or 'tool' is expressed using the Instrumental case without any preposition.
- Identify the agent (the doer) or the instrument used in the action.
- Change the agent/instrument noun into the Instrumental case (e.g., 'ruka' becomes 'rukom').
- Do NOT use the preposition 's/sa' when expressing the agent or means.

Smart Tips
Check if the word is a tool. If it is, use the Instrumental case and delete the preposition.
Always use the Instrumental case for the force of nature (wind, rain, fire).
If it's a person, use 'od strane'. If it's an object, use Instrumental.
Remember the plural Instrumental ending is usually -ima for all genders.
تلفظ
Instrumental Endings
The ending -om is usually short, but the preceding vowel might carry a rising accent.
No Preposition Pause
Since there is no 's', the participle and the instrumental noun should flow together without a pause.
Passive Statement
Vrata su otvorena ↘ ključem.
Falling intonation at the end of the sentence emphasizes the instrument.
حفظ کنید
روش یادسپاری
Instrumental is the 'Instrument' — use it for the tool, but keep the 's' out of the pool!
تداعی تصویری
Imagine a giant hand (the Agent) holding a hammer (the Instrument) hitting a nail. The hammer is the noun in the Instrumental case, and there is no 's' bridge between the hand and the hammer.
Rhyme
Kad je pasiv u pitanju, 's' je u skitanju; instrumental sam stoji, nikoga se ne boji.
Story
A master builder named Ivan built a cathedral. In the history books, they didn't say 'Ivan built it.' They said 'Katedrala je građena kamenom' (The cathedral was built with stone) and 'Katedrala je dovršena trudom' (The cathedral was finished with effort). The stone and the effort are the heroes in the Instrumental case.

سوالات متداول (8)
Only if you mean 'in the company of'. For example, 'Vrata su otvorena s osmijehom' (The door was opened with a smile). But for tools, never use 's'.
Because using the Instrumental for people can sound like they are objects. `Od strane` + Genitive is the standard way to show respect and clarity for human agents.
Yes, but the endings change. Masculine/Neuter usually take `-om` or `-em`, and Feminine takes `-om`.
It's common for tools (`nožem`, `ključem`), but for abstract causes, it's more common in news and writing.
Put them all in the Instrumental plural: `Vrata su otvorena ključevima`.
No, the 'se' passive (e.g., `Vrata se otvaraju`) usually doesn't take an Instrumental agent. Use the `biti` + participle passive instead.
Ask yourself: 'Is this the thing doing the work?' If yes, no 's'. If it's just 'along for the ride', use 's'.
Usually, the Instrumental agent comes at the end of the sentence for emphasis.
