'unjustly-owned' originates from the combination of 'unjustly' and 'owned'. 'Unjustly' comes from the word 'unjust', which originates from Latin 'iniustus', where 'in-' meant 'not' and 'iustus' meant 'just'. 'Owned' comes from Old English 'āgen', meaning 'to possess'.

'Unjustly' evolved from the Latin 'iniustus' through Old French 'injuste', and eventually became the modern English word 'unjust'. 'Owned' evolved from Old English 'āgen' to the modern English 'own'.

Initially, 'unjustly' meant 'not just', and 'owned' meant 'to possess'. Together, they describe possession without fairness, which has remained consistent.
