the compound adjective "wage-earning" is a modern english formation that directly combines two anglo-saxon and germanic roots with a productive english suffix. the first element, "wage," entered english via norman french, carrying its frankish sense of a pledge or security, which evolved to mean regular payment for service. it is paired with "earn," a native english verb from a germanic root meaning to harvest or gain through labor. the suffix "-ing" transforms the verbal action into an adjectival form describing the state or characteristic. thus, the term's literal logic is "characterized by gaining a payment pledge," which perfectly encapsulates the modern concept of working for a salary or wages.
