'presidency' originates from the Latin word 'praesidentia', where 'prae-' meant 'before' and 'sedere' meant 'to sit'.

'praesidentia' transformed into the French word 'présidence', and eventually became the modern English word 'presidency'.

Initially, it meant 'the act of presiding', but over time it evolved into its current meaning of 'the office of the president'.
