'reparably' originates from Latin, specifically the word 'reparabilis,' where 're-' meant 'again' and 'parabilis' meant 'able to be prepared or obtained.'

'reparabilis' transformed into the Old French word 'reparable,' and eventually became the modern English word 'reparable,' with 'reparably' as its adverbial form.

Initially, it meant 'able to be repaired,' and this meaning has largely remained the same in modern usage.
