Expert writing Tips
Best practice
When using "affected by", clearly specify what is causing the effect and what is being affected for clarity. For instance, instead of saying "The community was affected", specify "The community was affected by the recent storm".
Common error
A common mistake is using "affect" (verb) in place of "effect" (noun) or vice versa. Remember that "affect" means to influence, while "effect" refers to a result or consequence. For example, use "The policy affected the economy" (influence) and "The effect of the policy was significant" (result).
