'efficiently-made' originates from the word 'efficient,' which comes from Latin, specifically the word 'efficiens,' where 'efficere' meant 'to accomplish.'

'efficiens' transformed into the Old French word 'efficient,' and eventually became the modern English word 'efficient' through Middle English.

Initially, it meant 'capable of producing a desired effect,' and over time it evolved into its current meaning of 'achieving maximum productivity with minimum wasted effort or expense.'
