同義詞
反義詞
  • keep

    to continue having something

  • gain

    to obtain something new

文法句型

lose + noun phrase (person/job/possession)

用法筆記

Subject is usually a person or a community. When referring to death, the cause often follows the pattern 'lose someone to [cause]' (e.g. lost her father to cancer). Distinguish from sense 1 (MISPLACE): here the loss is permanent and not about forgetting where something is.

常見錯誤

I lost my job because I decided to quit.
I lost my job when the company downsized.
💡'Lose a job' means it was taken away from you, not that you left voluntarily.

文法句型

lose + abstract noun (interest, hope, faith, temper, patience)

用法筆記

Common in fixed phrases: 'lose your temper' (get angry), 'lose your nerve' (become scared), 'lose faith/trust' (stop believing). These are often idiomatic and the exact collocation cannot be guessed.

常見錯誤

She lost to study hard.
She lost the desire to study hard.
💡'Lose' needs a noun object; it cannot be directly followed by a verb.

反義詞

    to increase in amount or quantity

  • put on

    specifically for weight

文法句型

lose + noun phrase (hair, weight, leaves, colour)

用法筆記

Commonly progressive: 'I am losing my hair.' Use 'lose weight' for intentionally or unintentionally becoming lighter. Distinguish from sense 2 (LOSE THROUGH DEATH): here the change is gradual and natural, not caused by a sudden event.

常見錯誤

I am losing my weight very quickly.
I am losing weight very quickly.
💡'Weight' is used without a possessive pronoun in this context.

The sales team lost a great opportunity when they rejected the offer.

lose + opportunity / chance

同義詞
  • waste

    stronger, more direct; can imply fault

  • squander

    more dramatic, suggests a serious missed chance

反義詞

文法句型

lose + time/opportunity

lose + noun + -ing

用法筆記

The fixed phrase 'no time to lose' means you must act immediately. The -ing form follows the object of time (e.g. 'lost time waiting'). For wasting financial resources, see sibling sense 8 (LOSE MONEY).

常見錯誤

I lost time to wait for him.
I lost time waiting for him.
💡After 'lose time,' use the -ing form of the verb, not the infinitive.

釋義

when a timepiece runs at a speed that is too slow, causing it to show a time that is earlier than the real time

clock/watch + loses + time period

The clock in the library loses time, so the bell rings late each hour.

同義詞
反義詞
  • gain

    when a clock goes too fast

  • run fast

    the opposite behaviour

文法句型

clock/watch + loses

clock/watch + loses + time period

用法筆記

The opposite of 'lose' in this sense is 'gain' (a clock that runs fast gains time). This sense is less common in American English, where 'runs slow' is preferred instead.

常見錯誤

My watch losses five minutes every day.
My watch loses five minutes every day.
💡'Losses' is a noun; the third-person singular verb is 'loses.'

反義詞
  • gain

    for weight ('gain weight')

  • put on

    informal, opposite of losing weight

文法句型

lose + noun phrase

用法筆記

Object is typically something undesirable (weight, fat, a habit, a fear). Not used for deliberately discarding objects — use 'throw away' or 'get rid of' instead.

常見錯誤

I lost my old sofa last weekend.
I got rid of my old sofa last weekend.
💡'lose' means unintentionally no longer having something; use 'get rid of' for deliberate removal.

lose + amount + on + noun

用法筆記

Common with amounts of money and the preposition 'on' (e.g. 'lost $500,000 on the deal'). Frequently appears in business news and financial reports. The passive form ('money was lost') is also common.

常見錯誤

The shop lost money last month, but it still made a profit.
The shop lost money last month, so it did not make a profit.
💡'lose money' and 'make a profit' are opposites; they cannot both be true at the same time.

    active opposite ('beat the other team')

文法句型

lose + noun (game, match, election)

lose (no object)

用法筆記

Can be used transitively ('lose a game') or intransitively ('they lost again'). The preposition 'to' introduces the opponent: 'lose to someone'. Not used for failing an exam — use 'fail' instead.

常見錯誤

I lost my driving test.
I failed my driving test.
💡'lose' is for competitions with opponents; 'fail' is for tests and exams.

    explicit ('fail to catch the name')

文法句型

be lost in + noun phrase

lose + noun (words, sounds, meaning)

用法筆記

Common in the passive voice ('be lost in', 'be lost on'). 'Lost on someone' means the person fails to understand or appreciate something. 'Lost in something' means the sound or words are drowned out.

常見錯誤

I lost the movie because I was late.
I missed the beginning of the movie because I was late.
💡'lose' means failing to catch sensory input; 'miss' is for not arriving in time for an event.

文法句型

lose sight of + noun phrase

用法筆記

Almost always used with 'sight of' — 'lose sight of someone/something'. The 'escape' meaning ('lose a pursuer') typically implies physical pursuit. For abstract figurative use ('lose sight of your goals'), see the primary chunk.

常見錯誤

I lost my keys' (when meaning you misplaced them).
I lost sight of my keys' means you could see them a moment ago but now cannot. Use sense 1 (misplace) for everyday disappearance from your possession.
