'unjustly-distributed' originates from the combination of 'unjustly' and 'distributed'. 'Unjustly' comes from 'unjust', which originates from Latin 'iniustus', where 'in-' meant 'not' and 'iustus' meant 'just'. 'Distributed' comes from Latin 'distribuere', where 'dis-' meant 'apart' and 'tribuere' meant 'to assign'.

'Unjustly-distributed' evolved from the combination of 'unjustly' and 'distributed', both of which have roots in Latin.

Initially, 'unjustly-distributed' meant 'not fairly assigned', and this meaning has largely remained the same in modern usage.
