Expert writing Tips

Best practice

For clarity, use more descriptive verbs like "completed", "performed", or "executed" instead of "done" to specify the nature of the action. Consider also adding "the" like so "completed on the day" or "performed on the day" for improved readability.

Common error

Avoid relying solely on the passive construction "was done on" as it can obscure the actor. Instead, rephrase to highlight who performed the action, leading to clearer and more engaging writing. For example, instead of "The analysis was done on day 5", write "The researchers analyzed the samples on day 5".
