Expert writing Tips
Best practice
When using "which were", ensure the preceding noun is clearly defined to avoid ambiguity. For example, instead of "The results, which were surprising, led to new research", clarify as "The initial results, which were indeed surprising, led to new research directions."
Common error
Avoid using "which were" when "that were" is more appropriate for restrictive clauses (clauses essential to the sentence's meaning). "That" should be used if removing the clause changes the sentence's core meaning, while "which" is suitable for non-restrictive (added information) clauses.
