'charger' originates from Old French, specifically the word 'chargier,' where 'charg-' meant 'to load or burden.'

'chargier' transformed into the Middle English word 'chargeour,' and eventually became the modern English word 'charger.'

Initially, it meant 'to load or burden,' but over time it evolved into its current meanings of 'a device for charging' and 'a large dish.'
