/ɪmˌpɛtʃuˈɒsɪti/
鲁莽,冲动;指不经深思熟虑就急于行动的性格或行为特征。
源自拉丁语 impetuositas,由 impetus(冲击、猛冲)派生而来。Impetus 本身由前缀 **in-**(向内、朝向)和 petere(追求、冲向)构成。该词经由古法语 impetuosité 传入英语,保留了"猛烈冲动、不加克制"的核心含义。名词后缀 -osity 表示一种性质或状态。
His impetuosity often leads him into trouble.
他的鲁莽常常给他带来麻烦。
The general's impetuosity in ordering the charge without proper reconnaissance cost his troops dearly, and the battle was lost before it had truly begun.
将军在未经充分侦察的情况下便冲动地下令冲锋,这让他的部队付出了惨重的代价,战斗还未真正开始便已落败。
