Expert writing Tips
Best practice
When using "were retained by", ensure that the subject clearly indicates what is being kept or maintained, and the object specifies who or what is doing the retaining. This ensures clarity and avoids ambiguity in your writing.
Common error
Avoid overusing the passive voice with "were retained by", as it can sometimes make your writing sound less direct and less engaging. Consider using the active voice to emphasize the actor, for example, instead of saying "The documents were retained by the legal team", say "The legal team retained the documents".
