Expert writing Tips

Best practice

Avoid using the phrase "exactly proof" in formal writing. Opt for clearer alternatives like "definitive proof" or "conclusive evidence" for better readability and grammatical correctness.

Common error

Don't use "exactly" to modify "proof" directly. "Exactly" typically describes the precision of something else. Instead, focus on strengthening the adjective describing the proof itself, such as "definitive" or "irrefutable".
