'unjustly-released' originates from the combination of 'unjustly' and 'released'. 'Unjustly' comes from the word 'unjust', which originates from Latin 'iniustus', where 'in-' meant 'not' and 'iustus' meant 'just'. 'Released' comes from Old French 'reles', which meant 'to let go'.

'unjustly' changed from the Latin word 'iniustus' and eventually became the modern English word 'unjustly'. 'Released' evolved from the Old French word 'reles' and became the modern English word 'released'.

Initially, 'unjustly' meant 'not just', and 'released' meant 'to let go'. Over time, 'unjustly-released' evolved to mean 'released without fairness or justice'.
