'accurately' originates from Latin, specifically the word 'accuratus,' where 'ad-' meant 'toward' and 'curare' meant 'to take care of.' 'Confirmed' originates from Latin, specifically the word 'confirmare,' where 'con-' meant 'together' and 'firmare' meant 'to strengthen.'

'accuratus' transformed into the Old French word 'acuratus,' and eventually became the modern English word 'accurate.' 'Confirmare' transformed into the Old French word 'confirmer,' and eventually became the modern English word 'confirm.'

Initially, 'accurate' meant 'done with care,' and 'confirm' meant 'to strengthen or establish.' Over time, they evolved into their current meanings of 'precise' and 'verify.'
