نیستم، نیستی، نیست، نیستیم، نیستید، نیستند
Negative Forms of Be
خوب نیست means it is not good. اینجا نیستم means I am not here.
How It Works
| Person | Negative form |
|---|---|
| من | نیستم |
| تو | نیستی |
| او | نیست |
| ما | نیستیم |
| شما | نیستید |
| آنها | نیستند |
Change خوبم. to خوب نیستم. when you mean “I am not well.” Change اینجا آب هست. to اینجا آب نیست. when you mean there is no water here. The negative form belongs after the description or place phrase.
نیست is the learned negative stem here. Do not make ناست or نهست by attaching the usual verb-negative prefix to است or هست. نه on its own answers “no”; it does not replace the person-marked negative copula inside a full clause.
Everyday Iranian often shortens second- and third-person plural endings: نیستین and نیستن correspond to written نیستید and نیستند. Keep a formal text’s forms consistent.
