    stronger; implies long-term moral damage, not a single payment

文法句型

用法筆記

Object is normally a person with authority or influence (a judge, official, witness, voter). Often appears in passive ('be bought') or negative ('can't be bought'). Distinct from sense 3, which specifically targets silence about a secret.

常見錯誤

❌They bought the mayor a lot of money.
✅They bought the mayor with a lot of money.' or 'They bribed the mayor.
💡for the bribe meaning, the cash goes after 'with', not as a second object.

3.動詞及物C1
釋義

同義詞
  • silence

  • hush up

    informal; focus is on covering up the story itself, not paying a person

  • pay off

    very informal; broader — covers any payment to make a problem go away

文法句型

buy + somebody

buy + somebody's + silence

用法筆記

Differs from sense 2 ('BRIBE') in that the goal is specifically silence about something already known, not getting someone to perform a dishonest act. Often paired with the noun 'silence' (also 'buy somebody's silence').

常見錯誤

❌They bought him to keep quiet about the affair.
✅They bought his silence about the affair.' or 'They paid him to keep quiet about the affair.
💡for the silence meaning, prefer 'buy somebody's silence' or rephrase with 'pay'.

4.動詞及物B2
釋義

相信；採信

接受對方說法為真（多用於懷疑語氣）

例句

  • fall for

    informal; suggests the listener was tricked into believing

反義詞
  • doubt

    to feel uncertain that something is true

  • reject

    to refuse to accept a claim or idea

文法句型

buy + something (story / excuse / explanation)

buy + that-clause

用法筆記

Most common in negative sentences ('I don't buy it') and questions ('Do you really buy that?'). Object is typically a story, excuse, claim, or that-clause — not a concrete object, which would trigger sense 1.

常見錯誤

❌I don't buy you.
✅I don't buy your story.' or 'I don't believe you.
💡you 'buy' a claim or excuse, not a person, in this sense.

5. (of an amount of money) to have a value high enough that it covers the cost of a

5.動詞及物C1
釋義

夠買；買得起

例句

money + won't buy + somebody + something

subject is a sum / salary

同義詞
  • afford

    person-subject opposite frame ('she can afford it' vs 'her salary buys it')

  • cover

    neutral; the money is enough to pay the cost

  • stretch to

    informal British; the amount is just barely enough

文法句型

money + buys + something

what + money + can / cannot + buy

用法筆記

Subject must be an amount of money, a salary, or a similar measure of wealth — not a person. Often appears in negative or 'cannot' patterns to make a point about the limits of money.

常見錯誤

❌He buys a small flat with his salary.' (when meaning: his salary is enough for a flat)
✅His salary buys a small flat.
💡to express what an amount is enough for, the money itself must be the subject.

6. to win a result, advantage, or quality by giving up or losing something else tha

6.動詞及物C1
釋義

以代價換得

付出重要代價而得到

to win a result, advantage, or quality by giving up or losing something else that was important to you.

同義詞
  • gain

    neutral; does not always imply a heavy price was paid

    more formal; often used about agreements, peace, freedom

反義詞
  • lose

    the opposite outcome — not gaining, regardless of price

文法句型

buy + something + with + something

be bought + with + something

用法筆記

Object is normally an abstract gain (peace, freedom, victory, fame). The price is introduced by 'with', 'at the cost of', or 'by + -ing'. Often passive when the gain is the focus.

常見錯誤

❌They bought peace from a long war.
✅They bought peace with the lives of many soldiers.' or 'They bought peace at a great cost.
💡the price is introduced by 'with' or 'at the cost of', not 'from'.
