'affeer' originates from Old French, specifically the word 'afeurer,' where 'a-' meant 'to' and 'feurer' meant 'to fix or settle.'

'afeurer' transformed into the Middle English word 'afferen,' and eventually became the modern English word 'affeer.'

Initially, it meant 'to fix or settle a value,' but over time it evolved into its current meaning of 'to confirm or ratify.'
