- 1耗盡、使枯竭(存量、資源、體力被用到所剩無幾)
When you deplete something, you use it or take it away until much less is left — often until it is nearly gone. We say this about stores of things that can run out: money, oil, fish in the sea, soil, a battery, a person’s strength. A long drought can deplete a reservoir. Hours of extra work can deplete your energy. It is a rather formal, “serious” word; in everyday talk people more often say use up, run out of, or drain. Though actually, it began as a doctors’ word in the 1700s: physicians thought they were emptying something harmful out of the body. Almost nobody uses it that medical way now. You deplete a supply, a resource, or someone’s energy — you do not usually deplete a room of people (that is closer to empty or ).
組成Borrowed from Latin dēplētus (“empty”), from depleō. First attested in 1716; originally a medical term. de- (away, down to empty) plus a Latin root meaning “to fill” — so the old picture is “empty out what was filled”.
