impoundment(名词)
/ɪmˈpaʊndmənt/
The police ordered the impoundment of the car.
警方下令暂扣这辆车。
After heavy rains, the new dam increased the river’s impoundment, which improved irrigation but also flooded some nearby habitat.
暴雨之后,新建大坝增加了河流的蓄水量,虽然改善了灌溉,但也淹没了附近的一些栖息地。
impoundment 来自动词 impound(扣押;圈起并限制),由 **in-**(使进入/使处于)+ pound(古义指“围栏、圈地”,并非“磅/打击”)构成,后接名词后缀 -ment 表示“行为、过程或结果”。因此本义带有“把东西关进围栏/限制起来”的意象,后来引申到“依法扣押”与“拦蓄水体”。
