1
use resources such as time or money
To use time, energy, money, or other resources for a special reason or goal.
用法パターン：
to expend [time/effort/money/resources] on [something]
よくある間違い：
Learners often confuse "expend" with "expand" because they look similar. "Expend" means to use resources, while "expand" means to grow or become larger. Another mistake is using "expend" in very casual situations where native speakers would say "spend" or "use" instead, making the sentence sound too formal (e.g., saying "I expended ten dollars on lunch" instead of the more natural "I spent ten dollars on lunch").
類義語
spend (Common in everyday speech, especially with money and time; less formal than "expend".)
|
use (Very general and common; does not strongly suggest a large amount or cost in the way "expend" can.)
|
invest (Suggests using resources with the hope of a future benefit; often about money or time in a positive way.)
対義語
conserve (Means to protect and avoid using resources, which is the opposite of expending them.)
|
save (Means to keep money, time, or energy instead of using it.)

use up a fixed supply
To use all of something like fuel or bullets so that there is none left.
用法パターン：
to expend [ammunition/fuel/a device]
よくある間違い：
Learners may not realize this sense is more technical and is often used with physical supplies like fuel, ammunition, or missiles. They might overuse it in normal situations where "use up" or "finish" would be more natural. Also, some confuse the active "to expend ammunition" with the passive structure "the ammunition was expended" and think they are different meanings, when they are actually the same sense.
類義語
use up (More informal phrasal verb; commonly used in everyday speech instead of the more technical-sounding "expend".)
|
consume (Often used in technical or scientific contexts for fuel, energy, or materials; slightly broader but similar in tone.)
対義語
replenish (Means to fill something up again, which reverses the result of expending a supply.)
|
preserve (Means to keep something from being used or damaged, the opposite of using it up.)
