'satisfactorily' originates from Latin, specifically the word 'satisfacere,' where 'satis' meant 'enough' and 'facere' meant 'to do or make.'

'satisfacere' transformed into the Old French word 'satisfaire,' and eventually became the modern English word 'satisfy,' from which 'satisfactorily' is derived.

Initially, it meant 'to do enough,' but over time it evolved into its current meaning of 'in a manner that fulfills expectations or requirements.'
