tremor

A tremor is not just about earthquakes. It can mean a slight shaking of the ground, but it can also mean a small, unwanted shaking in your body, perhaps from cold, fear, illness, or even too much caffeine.

If you feel a tremor under your feet, it may be a small earthquake. But if your hands shake when you try to write, that is also a tremor. In stories, the word can also point to a slight physical sign of fear, excitement, or worry.

A tremor is a small shaking movement, and it can appear in several ways. Many people first think of a tremor as a slight earthquake: a brief shaking of the earth's surface. For example: "The seismograph detected a minor tremor near the fault line."

But the word is also often used for the body. It can describe a slight shaking in a hand, leg, or voice caused by cold, fatigue, fear, stress, or a medical condition. For example: "Her hands moved with a slight tremor as she reached for the medicine."

The word can also be used in a more literary way. A writer may describe a tremor in someone's voice, face, or body to show fear, excitement, anger, or uncertainty. Sometimes it appears in phrases such as "a tremor of fear" or "a tremor of hope," where the idea is a small but clear emotional stir.

The word comes from the Latin tremere, meaning "to tremble." Across these uses, the core idea stays the same: a small shaking that shows movement, weakness, tension, or change. Whether you are describing the ground, the body, or a person's emotional state, a tremor suggests that something is not fully steady.
