Best practice

When using "must be returned", ensure the context clearly indicates who is responsible for returning the item and to whom or where it should be returned. This clarifies the obligation and avoids ambiguity.

Common error

Avoid using "must be returned by itself" without specifying the subject. For example, instead of saying "The book must be returned", specify "The book must be returned by the student" to clarify who has the responsibility.
