* (having been proved) unproven
As the past participle of prove, proven is often discouraged, with proved preferred – “have proved” rather than “have proven”. However, today in everyday use they are both used, about equally.
Historically, proved'' is the older form, while proven''' arose as a Scottish variant – see . Used in legal writing from mid 17th century, it entered literary usage more slowly, only becoming significant in the 19th century, with the poet among the earliest frequent users (presumably for reasons of meter). In the 19th century, '''proven was widely discouraged, and remained significantly less common through the mid 20th century (''proved being used approximately four times as often), by the late 20th century it came to be used about equally.
As an attributive adjective, proven is much more commonly used, and proved is widely considered an error – “a proven method”, not *“a proved method”.
