Usage Note:
Proved is actually the older form of the past participle; proven is a Scottish variant that was first introduced into wider usage in legal contexts: The jury ruled that the charges were not proven. Both forms are now well established in written English as participles: He has proved (or proven) his point. The claims have not been proved (or proven). However, proven is more common when the word is used as an adjective before a noun: a proven talent.
