French Phrase
Je suis pas sûr.
Meaning
This phrase is a common, slightly informal way to express doubt or uncertainty. It is a contracted version of the grammatically formal 'Je ne suis pas sûr,' omitting the 'ne' which is typical in everyday spoken French. It conveys a lack of certainty about a fact, a decision, or a situation.
When to use
Use this in casual or everyday conversations with friends, family, or colleagues when you aren't 100% certain about something. It is the standard way to express doubt in modern spoken French.

✕Common Mistakes

In French, you 'are' sure (être), you don't 'have' sure (avoir).
Je ne pas sûr.
You must include the verb 'suis' (am) for the sentence to be grammatically correct.

Cultural Tip
In everyday spoken French, the negation particle 'ne' is almost always dropped. Using 'Je suis pas' instead of 'Je ne suis pas' will help you sound more natural and fluent. Note that while 'sûr' and 'sûre' sound identical, the spelling changes based on the gender of the person speaking.
