Expert writing Tips
Best practice
Always ensure subject-verb agreement. When using "effect" to describe a positive outcome, choose the correct singular or plural form to match the context. Instead of saying "a positive effects", use "a positive effect" for a singular result or "positive effects" for multiple outcomes.
Common error
Avoid using "a" with a plural noun. "A" indicates a singular item. Saying "a positive effects" incorrectly mixes singular and plural forms. Always pair "a" with a singular noun: "a positive effect".
