unproved

Meanings

1. 1
   adj

   not demonstrated, established, or confirmed by proof or sufficient evidence

   The theorem remains unproved despite extensive numerical evidence in its favor.

Formed from un- ("not") + proved, the past participle of prove. Prove came through Old French from Latin probare ("to test, approve, demonstrate"), based on probus ("good, worthy"). Unproved and unproven overlap, though unproved is especially natural for mathematical claims.
