quaver

Imagine a tiny bird singing: its notes might quaver, trembling just a little. Most often, the word describes a voice that shakes because of fear, sadness, age, or strong feeling. It can also describe a light physical trembling, like a leaf in the wind or a hand that is not fully steady. The movement is gentle, not sudden or violent.

Picture someone trying to speak bravely while holding back tears; their voice might quaver. Or think of a candle flame that seems to shake in the dark. In British English music, a quaver is also an eighth note.

To quaver means to tremble or shake, usually in the voice, but also in physical movement or light. It suggests a delicate, unsteady vibration rather than a violent shaking. The origin of the word is linked to the Middle English quaveren, which is thought to be an imitative sound for the act of trembling itself.

Most commonly, you'll encounter quaver describing someone's voice. A voice that quavers might betray nervousness ("Her voice quavered as she began her speech"), deep emotion ("His voice quavered with grief"), or the frailty of age ("The old man's voice quavered with each word"). It implies a lack of firmness—a vulnerability expressed through sound.

However, quaver isn't limited to voices. Something can quaver if it trembles physically—like a flag in a light breeze. You might also describe light as quavering if it flickers or dances uncertainly, such as a reflection on moving water.

In the world of music, especially in British English, a quaver is the official name for an eighth note. Historically, the term also referred to a musical "shake" or trill, which captures the same sense of rapid, tiny vibrations. Whether describing a shaky voice, a trembling leaf, or a flickering flame, quaver evokes a sense of delicate instability and subtle vibration—a gentle tremor that hints at underlying emotion or fragility.
