Best practice
Avoid using "was effected by" in formal writing. Instead, opt for more precise and grammatically accepted alternatives such as "was influenced by" or "was impacted by" to ensure clarity and correctness.
Common error
Many writers mistakenly use "effected" when they mean "affected". Remember that "affect" (with an 'a') typically functions as a verb meaning to influence, while "effect" (with an 'e') is usually a noun meaning a result or consequence. Therefore, use "was affected by" to show influence.
