'efficiency-centered' is a compound word formed from 'efficiency' and 'centered'. 'Efficiency' originates from Latin, specifically the word 'efficientia', where 'efficere' meant 'to accomplish'.

'efficiency' evolved from the Latin word 'efficientia' through Old French 'efficient' and eventually became the modern English word 'efficiency'.

Initially, 'efficiency' meant 'the ability to accomplish something with the least waste of time and effort', and this meaning has largely remained the same in modern usage.
