Questions & Answers about Zatvori prozor, jer je sada hladno.
Zatvori is the imperative form, used to give a command or instruction. In this sentence, it means close.
More specifically, it is:
- 2nd person singular imperative
- used when speaking to one person informally
So:
- Zatvori prozor. = Close the window.
If you were speaking formally to one person, or to several people, you would usually say:
- Zatvorite prozor. = Close the window.
In Serbian, subject pronouns are often left out when they are already clear from the verb form.
The verb zatvori already tells you that the command is addressed to you (singular, informal), so adding ti is usually unnecessary.
- (Ti) zatvori prozor.
The pronoun ti can be added for emphasis, but normally it is omitted.
Here, prozor is the direct object of the verb zatvori, so it should be in the accusative case.
