Questions & Answers about Tko može otvoriti prozor?
What does each word in the sentence do?
- Tko — interrogative pronoun meaning who (nominative).
- može — 3rd person singular present of moći (can).
- otvoriti — infinitive to open (perfective aspect).
- prozor — window; masculine inanimate noun in the accusative singular (which looks the same as the nominative for inanimate masculines).
Why is the verb in the singular (može) even though more than one person might be able to do it?
Because tko is grammatically singular. With tko, the verb is always in the 3rd person singular: Tko može…? Saying Tko mogu…? is ungrammatical. Even in phrases like Tko od vas može…? the verb stays singular.
Can I say ko instead of tko?
In standard Croatian, use tko. The form ko is standard in Serbian and common in Bosnian; in Croatia it’s heard colloquially but is non‑standard in writing. Related forms in Croatian keep the t: netko (someone), nitko (no one), itko (anyone, typically in questions/negatives).
How would I ask “Can someone/anyone open the window?” instead of “Who can…?”
