'discharge' originates from Old French, specifically the word 'descharger,' where 'des-' meant 'away' and 'charger' meant 'to load.'

'descharger' transformed into the Middle English word 'discharge,' and eventually became the modern English word 'discharge.'

Initially, it meant 'to unload or release,' but over time it evolved into its current meaning of 'to release from a duty or obligation.'
