How to Say "I Am Not" in Serbian: nisam, nisi, nije
If you already know how to say "I am" in Serbian, the negative looks like it should be easy — just add "ne", right? Not quite. The verb biti (to be) is special: it fuses the negation into a single word built on "ni-". So the six forms are nisam, nisi, nije, nismo, niste, nisu — the negative twins of sam, si, je, smo, ste, su. You never split off a separate "ne". Say "Nisam umoran." for "I am not tired," or "On nije ovde." for "He is not here." There's a bonus, too: while the positive je is a weak clitic that can't open a sentence, the strong nije happily stands alone, so "Nije." is a complete answer. Just remember this fusion is only for biti — other verbs keep the separate ne.
Examples
- Nisam umoran. I am not tired.
- On nije ovde. He is not here.
- Nismo gladni. We are not hungry.

You learned to say I am in Serbian. Now you want to say I am not. The obvious move — sticking ne in front — is exactly the trap. Serbian fuses the not right into the verb.
-
Here's the core idea. Most Serbian verbs are negated with a separate little word ne in front. But the verb to be is special: its negative is a single fused word that already contains the not.
-
Look at how it's built. The positive forms are sam, si, je, and the negatives are nisam, nisi, nije. It's just ni plus the verb, glued together. One word, with the no already inside it.
-
Here's the full set so you can see the pattern. Nisam, nisi, nije in the singular; nismo, niste, nisu in the plural. Every one starts with ni — learn that single syllable and you've got all six. nisam, nisi, nije, nismo, niste, nisu
-
Let's put it to work. To say I am not tired, you don't say ne sam — you use the fused form nisam. Nisam umoran.
-
For he is not here, the is not is nije — again one word. Notice it can sit right after the subject, just like the positive je. On nije ovde.
-
And in the plural, we are not hungry uses nismo. Same logic — ni plus the ending for we. No extra ne anywhere. Nismo gladni.
-
There's a bonus you get for free. The positive je is a clitic — a weak little word that can't start a sentence. But the negative nije is strong: it can stand right at the front. So a one-word answer like Nije. meaning It isn't is perfectly natural. Nije.
-
Now the mistake almost every learner makes. Because other verbs take ne in front, people say ne sam or ne je for to be. That's wrong. The ne is already fused inside — say nisam, nije. nisam, nije
-
One nuance to keep straight: this fused trick is only for to be. Regular verbs still use a separate ne. I don't know is ne znam — two words. Only biti fuses. ne znam
-
So lock in three things. The negative of to be is one fused word starting with ni. Never add a separate ne. And unlike the positive je, the negative is strong enough to begin a sentence.
