'energizer' originates from the verb 'energize,' which comes from the Greek word 'energein,' where 'en-' meant 'in' and 'ergon' meant 'work.'

'energize' transformed from the Greek word 'energein' and eventually became the modern English word 'energize.'

Initially, it meant 'to put into action or work,' but over time it evolved into its current meaning of 'to give energy or vitality.'
