not sure
Lacking firm conviction
Not sure expresses uncertainty or a lack of confidence about something.
It functions as a hedging phrase when someone doesn't want to commit to a definite answer or position: I'm not sure if she's coming tonight.
The phrase can soften statements or signal genuine doubt, and ranges from polite deflection to honest admission of incomplete knowledge.
Not sure what you mean by that.
