'vicegerency' originates from Latin, specifically the word 'vicegerentia,' where 'vice-' meant 'in place of' and 'gerere' meant 'to carry or conduct.'

'vicegerentia' transformed into the Medieval Latin word 'vicegerentia,' and eventually became the modern English word 'vicegerency.'

Initially, it meant 'the office of a deputy,' but over time it evolved into its current meaning of 'the authority of a deputy or substitute.'
