'equitably-granted' originates from the combination of 'equitably' and 'grant'. 'Equitably' comes from the Latin word 'aequitas', meaning 'fairness', and 'grant' comes from the Old French word 'graanter', meaning 'to allow or permit'.

'Equitably' evolved from the Latin 'aequitas' through Old French 'equité', and 'grant' evolved from Old French 'graanter' to Middle English 'graunten', eventually forming the modern English 'grant'.

Initially, 'equitably' meant 'in a manner of fairness', and 'grant' meant 'to allow or permit'. Together, they evolved to mean 'given in a fair manner'.
