Questioning means asking questions to learn more or understand better. When you're questioning something, you're examining it carefully rather than accepting it at face value. You're curious, doubtful, or looking for deeper answers.

In school, a questioning student might raise their hand to ask why something works a certain way, not just memorizing what the teacher said. Scientists spend their careers questioning assumptions, running experiments to test whether popular beliefs actually hold up. A detective questions witnesses and suspects, trying to piece together what really happened.

The word can also describe an attitude of doubt or uncertainty. If you're questioning whether your friend told you the truth, you're not entirely sure you believe them. Someone might be questioning their own decisions, wondering if they made the right choice.

Questioning differs from simply being confused. Confusion means you don't understand. Questioning means you're actively seeking understanding or challenging what you've been told.
