'illicitly-aided' originates from the combination of 'illicitly,' derived from Latin 'illicitus,' meaning 'not allowed,' and 'aided,' from Old French 'aidier,' meaning 'to help.'

'illicitus' transformed into the English word 'illicit,' and 'aidier' became 'aid,' eventually forming the modern English term 'illicitly-aided.'

Initially, 'illicit' meant 'not allowed by law,' and 'aid' meant 'to help.' The combination retains the meaning of being helped in an unlawful manner.
