Proved and proven are both acceptable past participle forms of the verb prove. This means they can both be used in constructions that are classified as present perfect (as in I have proved or I have proven) or past perfect (as in I had proved or I had proven).

In these cases, these past participle forms are paired with a form of the helping verb (auxiliary verb) has. However, they can also be used in passive constructions that don’t use a helping verb, as in It was proved or It was proven.

While proved can also be used as the simple past tense form of prove, as in You proved me wrong, proven cannot (for example, it would be ungrammatical to say You proven me wrong).

Though both words can technically be used as adjectives, proven is far more commonly used this way, as in a proven method or a proven fact.

Here’s an example of proved and proven used correctly in the same sentence.

Example: This study has proved that it often takes a long period of time for things that have been scientifically proven to be accepted as proven facts by a majority of people.

The full Latin sentence is exceptiō probat rēgulam in cāsibus non exceptīs “The exception tests the rule in cases that are not excepted,” which makes clear the implied existence of a general rule: for example, “No parking on Saturdays and Sundays” implies that parking is allowed the other five days of the week.
