'forfeit' originates from Old French, specifically the word 'forfet,' where 'for-' meant 'outside' and 'fait' meant 'deed.'

'forfet' transformed into the Middle English word 'forfet,' and eventually became the modern English word 'forfeit.'

Initially, it meant 'a crime or offense,' but over time it evolved into its current meaning of 'penalty or loss due to wrongdoing.'
