Used to politely express doubt or hesitation about an idea, plan, or statement.
“I'm not sure about that - the last time we tried this route, we got stuck in traffic.”
“I'm not sure about that plan. What if it rains on the day of the picnic?”
In problem-solving conversations, this phrase often marks the moment a speaker disagrees or raises doubt before offering an alternative. It's a softer way of disagreeing, so listen for a 'but' or explanation that follows, which usually holds the real reason for the doubt. This phrase can help you identify which speaker is hesitant about a proposed solution.
Synonyms: I have my doubts, I'm hesitant about that, I'm not convinced
