Shaken means disturbed, upset, or unsettled by something surprising or frightening. When you're shaken, you feel off-balance emotionally, like your sense of calm or safety has been rattled.

Someone might feel shaken after a close call while riding their bike, or after hearing unexpected bad news. A person might be visibly shaken after a fire drill goes wrong. The word captures that moment when something jolts you out of your normal state, leaving you rattled, anxious, or struggling to regain your composure.

Being shaken is usually temporary. You might feel shaken for a few minutes after a scary moment, or for days after something more serious. It doesn't necessarily mean being permanently changed, just knocked off your emotional footing for a while.

People often say they need time to recover after being shaken by an experience, waiting until that unsettled feeling passes and they feel steady again.
