The term 'inefficiency-based' is a compound word formed from 'inefficiency' and 'based'. 'Inefficiency' originates from the Latin word 'inefficientia', where 'in-' meant 'not' and 'efficientia' meant 'producing an effect'.

'Inefficiency' evolved from the Latin 'inefficientia' through Old French 'inefficience', eventually becoming the modern English word 'inefficiency'.

Initially, 'inefficiency' meant 'not producing an effect', but over time it evolved to mean 'lack of efficiency or effectiveness'.
