Expert writing Tips
Best practice
Prefer using "for which purpose" or "with the purpose of" instead of "in which purpose" for better clarity and grammatical correctness. "For which purpose" often leads to a more concise and easily understood construction.
Common error
Avoid using "in which" when you intend to express purpose. "In which" is typically used to define a location or context, not the reason or aim. Instead, use phrases like "for which" or "with the intent to" to clearly indicate the purpose.
