'remorse' originates from Latin, specifically the word 'remorsus,' where 're-' meant 'again' and 'mordere' meant 'to bite.'

'remorsus' transformed into the Old French word 'remors,' and eventually became the modern English word 'remorse' through Middle English.

Initially, it meant 'to bite again,' but over time it evolved into its current meaning of 'deep regret or guilt for a wrong committed.'
