'inequitably-returned' originates from the combination of 'inequitable' and 'returned'. 'Inequitable' comes from Latin 'aequitas', meaning 'equality', with the prefix 'in-' indicating 'not'. 'Returned' is derived from Old French 'retourner', meaning 'to turn back'.

'Inequitable' evolved from the Latin 'aequitas' through Old French 'inequitable', and 'returned' from Old French 'retourner'.

Initially, 'inequitable' meant 'not equal', and 'returned' meant 'to turn back'. Together, they evolved to mean 'returned in an unfair manner'.
