文法句型

discolour

discolour + noun phrase

be discoloured by + noun phrase

用法筆記

Often used in the passive (be / get discoloured) when describing a result rather than a cause. The agent is typically introduced by from, not by: 'discoloured from sunlight' NOT 'discoloured by sunlight'. Do not use this word for natural or seasonal colour changes such as leaves turning in autumn — discolour always implies that the change is unwanted or unattractive.

常見錯誤

The leaves discoloured beautifully in autumn.
The leaves changed colour beautifully in autumn.
discolour always carries a negative meaning; it is not a neutral word for colour change.
The photo was discoloured by the sun.
The photo was discoloured from the sun.
with passive, the cause is best introduced by from, not by.
