Expert writing Tips

Best practice

Use "which describes why" when you need to add a clause that explains the reason behind a preceding statement. It's particularly useful in formal writing to provide clear and logical connections between ideas.

Common error

Avoid using "that" when "which" is appropriate for nonrestrictive clauses. "Which" introduces additional, non-essential information, while "that" introduces essential information. Omitting "which" shouldn't change the core meaning of the sentence.
