Definition:
Jitter describes a brief, involuntary movement often linked to nervous tension or sudden energy. It may show in a hand that won’t quite stay still or a thought that flickers too quickly to grasp. The sensation is sharp but fleeting, like a spark passing through. Jitters often arise in moments of anticipation or uncertainty, where the body reacts before the mind fully understands why. The word conveys a mix of motion and unease held in a split second.
