'acceptably' originates from the Latin word 'acceptabilis,' where 'acceptare' meant 'to take or receive.'

'acceptabilis' transformed into the Old French word 'acceptable,' and eventually became the modern English word 'acceptable,' with 'acceptably' as its adverbial form.

Initially, it meant 'to take or receive in a satisfactory manner,' and this meaning has largely remained the same in modern usage.
