常見錯誤
What are common mistakes with "Bolster"?Which "Bolster" sentences look correct but are wrong?
×We need to bolster the economy.
✓We need to bolster the economy.
The sentence is grammatically correct but often misused in context. 'Bolster' implies providing significant, often external, support to something that is weak or failing. It is not a synonym for general 'improvement' or 'maintenance'. Use it when adding support to something that needs strengthening.
×He bolstered his friend to apply for the job.
✓He encouraged his friend to apply for the job.
'Bolster' is used with abstract concepts like confidence, argument, position, or system. It is not used with a person as the direct object to mean giving emotional encouragement. Use 'encourage', 'support', or 'urge' instead.
×The company is bolstering.
✓The company is growing stronger. / The company is bolstering its market position.
'Bolster' is a transitive verb and requires a direct object. It cannot be used intransitively. You must specify what is being supported or strengthened.
×We should bolster against inflation.
✓We should hedge against inflation. / We should take measures to bolster the economy against inflation.
'Bolster' means to add support *to* something. The structure 'bolster against...' is incorrect. You bolster [something] against [a threat], or use other verbs like 'protect against', 'guard against', or 'hedge against'.
×The news bolstered.
✓The news was encouraging. / The news bolstered our hopes.
Similar to mistake #3, this is an incomplete sentence. 'Bolstered' as a verb needs an object. If you want to use it as an adjective, the past participle 'bolstered' can be used attributively (e.g., 'a bolstered defense'), but not predicatively without an object.
×Let's bolster the meeting.
✓Let's support the idea in the meeting. / Let's use the meeting to bolster our proposal.
'Bolster' collocates with abstract nouns like 'case', 'argument', 'position', 'confidence'. It does not collocate with events like 'meeting', 'party', or 'conference'. The focus is on strengthening an abstract concept, not an event itself.
