'fraudulently-obtained' originates from the Latin word 'fraus,' meaning 'deceit' and the Old French 'obtenir,' meaning 'to obtain.'

'Fraus' transformed into the Old French 'fraude,' and 'obtenir' evolved into the modern English 'obtain,' leading to the compound adjective 'fraudulently-obtained.'

Initially, it meant 'obtained through deceit,' and this meaning has largely remained the same in modern usage.
