'irrecoverably' originates from the Latin word 'recuperare,' where 're-' meant 'again' and 'cuperare' meant 'to gain or obtain.'

'recuperare' transformed into the Old French word 'recouvrer,' and eventually became the modern English word 'recover' through Middle English. The prefix 'ir-' was added to denote the negative form.

Initially, it meant 'to gain or obtain again,' but over time it evolved into its current meaning of 'in a manner that cannot be recovered.'
