cost-efficient

The compound adjective 'cost-efficient' is a modern formation, emerging in the 20th century from the fields of business and economics. It logically combines the noun 'cost', with its Latin roots in the concept of a fixed price or expenditure, with the adjective 'efficient', which originates from the Latin idea of bringing something about or accomplishing a task effectively. The fusion creates a term whose literal meaning is 'productive with respect to cost', directly evolving into its modern abstract sense of providing good value relative to the money spent. It represents a pragmatic linguistic development where two established concepts are merged to describe a key principle of modern resource management.

Structure: cost (expense) + efficient (productive) - cost: From Middle English 'cost', from Old French 'cost', from Latin 'constare' ('to stand at, to cost').

In this compound, it functions as an adjective meaning 'productive with minimum waste'.
