Expert writing Tips
Best practice
When starting a clause with "which is using", ensure that the "which" refers clearly and unambiguously to the noun it is modifying to avoid confusion.
Common error
Avoid using "which" when "that" is more appropriate. "Which" introduces nonrestrictive clauses (adds extra information but is not essential to the sentence), while "that" introduces restrictive clauses (essential to the sentence's meaning). If the clause is essential, use "that" instead of "which".
