tremor 指“颤抖;震颤”,常用于描述身体因紧张、疾病、寒冷等引起的轻微抖动,也可指地面发生的轻微地震/震动。(另有较专业用法,如金融市场的“震荡”,此处以常见义为主。)
/ˈtrɛmər/
His hands had a slight tremor from the cold.
他因为寒冷手有些轻微颤抖。
A tremor ran through the crowd as the news spread, and the room seemed to hold its breath.
消息传开时,人群中掠过一阵不安的震颤,整个房间仿佛都屏住了呼吸。
tremor 来自拉丁语 tremor,意为“颤抖”,源于动词 tremere(“发抖、战栗”)。因此它在英语里既可指身体的抖动,也常被引申为某种“轻微但可感的震动/波动”。
