Expert writing Tips
Best practice
When using "which is required", ensure that the clause it introduces adds essential information to the sentence. If the information is non-essential, consider using "which is optional" or removing the clause altogether for conciseness.
Common error
Avoid using "that" in place of "which" when introducing a nonrestrictive clause. "Which is required" is typically used in nonrestrictive clauses, meaning the information is additional but not essential to the sentence's meaning. "That" is used for restrictive clauses that are crucial to the sentence's meaning.
