The word 'inefficiency-centered' is a compound word formed by combining 'inefficiency' and 'centered'. 'Inefficiency' originates from the Latin word 'inefficientia', where 'in-' meant 'not' and 'efficientia' meant 'efficient'.

The term 'inefficiency' evolved from the Latin 'inefficientia' through Old French 'inefficience', and eventually became the modern English word 'inefficiency'.

Initially, 'inefficiency' meant 'lack of efficiency', and this meaning has largely remained the same in modern usage.
