power

Compared meaning: strength or force (noun).

比较义项：力量（名词）。

• power 本词

  Power is the everyday, register-neutral word for strength; it is common in ordinary speech and can also mean control, ability, or electricity, meanings might does not share.

  power是日常、语域中性的常用词，表示力量；除此以外还常表示控制力、能力或电力，这些用法might不具备。

  The boxer's punches showed incredible power.

  这位拳击手的拳头展现出惊人的力量。

• might

  Might is more formal and literary, emphasizing great physical or military strength; it often appears in set phrases such as 'with all your might' and lacks power's other meanings.

  might更正式、更文学化，强调巨大的力量（尤指体力或军事力量），常出现在如“with all your might”这样的固定搭配中，且不具备power的其他义项。

  He pushed against the boulder with all his might.

  他用尽全身力量去推那块巨石。

Both mean strength. Power is the everyday, neutral word for strength, and can also mean control or electricity. Might is formal and literary, for physical or military strength, often in phrases like 'with all your might'. Not compared: might as a modal verb, meaning 'possibility'.

这两个词在“力量”这一义项上意思相近，但语域和搭配不同：might更正式、更文学化，强调巨大的（尤指体力或军事）力量，常见于固定搭配；power则是日常、中性的常用词。这里不比较power的“电力”“控制力／权力”等其他义项，也不比较might作情态动词表示“可能”的用法。

Compared meaning: the energy that runs electrical devices (noun).

比较义项：使电器运转的能量／“电”这种能量形式（名词）。

• power 本词

  General, everyday word for the energy supply that runs things; often used loosely for electricity but can also mean other energy sources (solar power, horsepower); typical in fixed phrases like “power outage” or “power lines.”

  笼统、口语化地指驱动物品运转的能量供应；常被随意用作 electricity 的同义词，但也可以指其他能源（如太阳能 solar power、马力 horsepower）；常见于“power outage”（停电）、“power lines”（电线）等固定搭配。

  Fallen power lines blocked the road for hours after the storm.

  暴风雨过后，倒下的电线堵住了道路好几个小时。

• electricity

  The specific, technical name for this form of energy (electric current); used to name the energy itself, in science, billing, or formal contexts, and in fixed phrases like “static electricity.”

  这种能量形式（电流）的专业名称；用于指称这种能量本身，多见于科学、账单等正式语境，也用于“static electricity”（静电）这类固定搭配。

  Rubbing a balloon on your hair creates static electricity.

  用气球摩擦头发会产生静电。

Power and electricity both mean the energy that runs electrical things, and are often used the same way. Power is more general and casual, and can mean other energy types, like solar power. Electricity is the technical, formal name. Power's other meanings are not compared.

这两个词在“供电、电力”这个意义上很接近，日常口语中常可互换（比如“停电”既可以说 lost power，也可以说 lost electricity）。不过 power 是更笼统、口语化的说法，也能指其他能源（如太阳能 solar power、马力 horsepower），并常见于“power outage”“power lines”这类固定搭配；electricity 则是这种能量形式的专业名称，多用于科学、账单等正式语境，以及“static electricity”这类固定搭配。这里不比较 power 的其他义项，如“政治权力”“力量”“数学中的乘方”等。
