'irredeemably' originates from the Latin word 'redimere,' where 're-' meant 'back' and 'emere' meant 'to buy.' The prefix 'ir-' adds a negative connotation, indicating something that cannot be bought back or redeemed.

'redimere' transformed into the Old French word 'redimer,' and eventually became the modern English word 'redeem.' The prefix 'ir-' was added to form 'irredeemable,' and the adverbial form 'irredeemably' was derived from it.

Initially, it meant 'unable to be bought back,' but over time it evolved into its current meaning of 'unable to be corrected or saved.'
