基本释义
[verb] release from a leash or restraint
[动词] 从皮带或约束措施中放出来
深入解读
Unleash 一词最早出现于17世纪70年代，由前缀 un- （相反动作、取消、除去）+ leash （用皮带等系住、缚住、牵住狗、鹰等动物，作名词指“拴狗的皮带、链条”）构成，其本义即“解皮带放开”，比如：
从这个概念出发， unleash 很自然地就被用来引申指“突然释放、放纵……发出、使爆发”，多指突然使强大或暴力的力量、情绪、活动或群体等释放出来或者变得不受约束，比如：
几天之内，他就向首都发起了猛攻。
He unleashed an onslaught against the capital within days.那个脾气暴躁的老人把所有的怒气都发泄在我身上。
The full force of the grumpy old man's rage was unleashed against me.
