Expert writing Tips
Best practice
When attributing information, ensure that you accurately represent the original speaker's intent and context. Using "who stated that" is a neutral way to introduce a direct quote or paraphrase, but consider using more descriptive verbs (e.g., argued, suggested, claimed) to convey the speaker's attitude or purpose.
Common error
Avoid using "stated" repeatedly in your writing. While grammatically correct, overuse can make your writing sound monotonous. Vary your vocabulary by using synonyms like "asserted", "indicated", "mentioned", or "reported" to add nuance and clarity.
