Questions & Answers about Ja nisam slobodan sutra.
Why is ja included? Do I have to say it?
No. In Serbian, subject pronouns are often omitted because the verb form already shows the person.
So:
- Ja nisam slobodan sutra.
- Nisam slobodan sutra.
both mean I’m not free / available tomorrow.
Including ja adds emphasis or contrast, for example:
- Ja nisam slobodan sutra, ali on jeste.
I’m not free tomorrow, but he is.
In everyday speech, Nisam slobodan sutra is often the more natural choice unless you want to stress I.
Why is it nisam and not ne sam?
Because the negative form of sam (I am) is a single word: nisam.
This comes from the verb biti (to be). In the present tense, the negative forms are:
- nisam = I am not
- nisi = you are not
- nije = he/she/it is not
- nismo = we are not
- niste = you all / formal you are not
- nisu = they are not
So:
- Ja sam slobodan. = I am free.
- Ja nisam slobodan. = I am not free.
You should learn these as fixed forms.
