tremor
Body's nervous shake
A tremor is a slight shaking or vibration.
The earth tremors during earthquakes.
A person's hands may tremble from age, illness, or emotion: A tremor ran through her as she read the letter.
The word often suggests something small that portends something larger—a tremor of fear, a tremor in the voice.
In medicine, tremor refers to involuntary rhythmic muscle movements, as in Parkinson's disease.
