Expert writing Tips
Best practice
When using "which happens to", ensure the clause it introduces is nonrestrictive, meaning it provides additional, but not essential, information. Use commas to set it off from the main clause.
Common error
Avoid using "that happens to" when "which happens to" is grammatically correct. "Which" is appropriate for nonrestrictive clauses (additional information), while "that" is for restrictive clauses (essential information).
