'sufficiently' originates from Latin, specifically the word 'sufficere,' where 'sub-' meant 'under' and 'facere' meant 'to make or do.'

'sufficere' transformed into the Old French word 'suffisant,' and eventually became the modern English word 'sufficient' through Middle English.

Initially, it meant 'to meet the needs or requirements,' and this meaning has largely remained the same in modern usage.
