When you need to specify the source of a recommendation, use clearer phrasing such as "recommended by whom" or "recommended by which authority" for better clarity.
Common error
Avoid using "recommended by which" as it's grammatically awkward. Instead, rephrase to specify the recommending entity directly using "recommended by whom" or "endorsed by which".
