Expert writing Tips
Best practice
When using "affected by", ensure that the subject and the influencing factor are clearly identified to avoid ambiguity. For example, instead of saying "The results were affected", specify "The results were affected by the temperature change".
Common error
A common mistake is using "effect" as a verb instead of "affect". Remember, "affect" is typically a verb meaning to influence, while "effect" is typically a noun meaning a result. To avoid this error, double-check whether you intend to describe an influence or a result. For instance, use "The weather affected the game" (influence), not "The weather effected the game".
