Expert writing Tips
Best practice
When using "it could not be found" in formal writing, ensure the subject 'it' is clearly defined in the preceding context to avoid ambiguity. For instance, specify 'the document' or 'the evidence' before stating that it could not be found.
Common error
Avoid using "it could not be found by someone" when the actor is irrelevant or unknown. The passive voice is already implied in "it could not be found"; adding 'by someone' is redundant and weakens the sentence.
