The compound "wage-earner" is a transparent construction from three native English elements. The first element, "wage," originates from an Old North French term meaning a pledge or security, which evolved to signify regular payment for labor. It combines with the verb "earn," an Old English word meaning to gain or deserve through labor or merit. The agent suffix "-er," also from Old English, is appended to form a noun describing the person who performs the action. Thus, the term's literal logic is "a person who gains a pledge/payment," directly mapping to the modern concept of someone who works for a salary.
