'legally-financed' originates from the combination of 'legal' and 'finance', where 'legal' is derived from Latin 'legalis', meaning 'pertaining to the law', and 'finance' from Old French 'financer', meaning 'to pay a ransom'.

'legalis' transformed into the Old French 'legal', and 'financer' evolved into the modern English 'finance', eventually forming the compound adjective 'legally-financed'.

Initially, 'legal' meant 'pertaining to the law', and 'finance' meant 'to pay a ransom'. Over time, 'legally-financed' evolved to mean 'funded in a manner that complies with the law'.
