IPA: /ɪmˈpaʊndmənt/
KK: /ɪmˈpaʊndmənt/
A body of water created by holding back water, often in a reservoir, or the act of holding something back.
The impoundment of the river created a large lake that provided water for the nearby town.
Impoundment → It is formed from "im-" (meaning into) and "pound" (from Old French *pondrer*, meaning to place or put). The suffix "-ment" (meaning the action or result of) indicates the process or state of placing something into a confined space. Thus, impoundment refers to the act of placing something into a confined area, often used in the context of water or property.
Think of 'putting something into' ('im-') a 'place' ('pound') — that's why impoundment means to confine something.
