As evidenced by or As evident by: Which Is Correct?

Updated 2026-10-03 · Which One Is Correct editorial team

Quick answer: The correct phrase is always as evidenced by. The form as evident by is grammatically incorrect because it lacks the necessary passive voice structure. You must use the past participle evidenced to show that evidence supports a claim, rather than using the adjective evident.

The Short Answer

The only standard and grammatically correct form is as evidenced by. This phrase functions as a participial phrase that modifies the preceding statement by indicating supporting proof.

People often confuse the two because evident and evidenced sound similar in speech. Writers mistakenly replace the verb form with the adjective, not realizing that the sentence requires an action performed by the evidence rather than a static description.
