'deliberately' originates from Latin, specifically the word 'deliberatus,' where 'de-' meant 'down' and 'liberare' meant 'to weigh or balance.' 'Confirmed' originates from Latin, specifically the word 'confirmare,' where 'con-' meant 'together' and 'firmare' meant 'to strengthen.'

'deliberatus' transformed into the Old French word 'deliberer,' and eventually became the modern English word 'deliberate.' 'Confirmare' transformed into the Old French word 'confirmer,' and eventually became the modern English word 'confirm.'

Initially, 'deliberate' meant 'to weigh or consider carefully,' and 'confirm' meant 'to strengthen or establish.' Over time, 'deliberately-confirmed' evolved to mean 'intentionally verified.'
