Expert writing Tips
Best practice
Instead of using "a good effectiveness", opt for stronger and more grammatically correct alternatives such as "high effectiveness", "strong effectiveness", or "significant effectiveness" to improve clarity and impact.
Common error
Avoid using indefinite articles (a/an) before abstract nouns like "effectiveness" when describing a general quality. Instead, consider using adjectives that directly modify the noun or rephrasing the sentence to highlight the specific impact or result achieved.
