Common error
Avoid using "an unwarranted" when you simply mean that something is not desired. While something unwarranted is often unwanted, the term specifically implies a lack of justification or authorization. For example, a surprise gift might be unwanted but it is rarely described as unwarranted unless it violates a specific rule or boundary.
