'unequally-distributed' originates from the combination of 'unequal' and 'distributed'. 'Unequal' comes from Latin 'inaequalis', where 'in-' meant 'not' and 'aequalis' meant 'equal'. 'Distributed' comes from Latin 'distribuere', where 'dis-' meant 'apart' and 'tribuere' meant 'to assign'.

'inaequalis' transformed into the Old French word 'inequal', and eventually became the modern English word 'unequal'. 'Distribuere' transformed into the Old French word 'distribuer', and eventually became the modern English word 'distribute'.

Initially, 'unequal' meant 'not equal', and 'distributed' meant 'to assign or divide'. Over time, 'unequally-distributed' evolved to mean 'not evenly or fairly spread out'.
