'provable' originates from the Latin word 'probare,' where 'pro-' meant 'for' and 'bare' meant 'to test or prove.'

'probare' transformed into the Old French word 'prover,' and eventually became the modern English word 'prove,' from which 'provable' is derived.

Initially, it meant 'to test or try,' but over time it evolved into its current meaning of 'capable of being demonstrated as true.'
