Expert writing Tips

Best practice

Instead of using the grammatically questionable phrase "costed by", consider using more accurate and standard alternatives like "estimated by", "calculated by", or "assessed by" to maintain clarity and credibility in your writing.

Common error

Avoid using "costed by" as a passive construction, which implies the cost was acted upon. Instead, ensure the agent or entity performing the costing is clearly identified using phrases like "estimated by", or restructure the sentence to use an active voice such as "the department costed the project".
