The word 'wage' entered English from Old North French in the 14th century, carrying the sense of a pledge or a guarantee. This meaning is rooted in its ultimate Germanic ancestor, reflected in Old English 'wedd' (a pledge), which is related to the concept of giving security. Over time, the meaning shifted from the pledge itself to the payment given as a fulfillment of that pledge, particularly for services rendered. The verb sense, "to carry on (a war)", evolved from the idea of pledging oneself to or engaging in a struggle, connecting the core concept of a committed undertaking to its modern abstract meaning.

The word 'wage' is a simplex form. It originates from the Old North French 'wage' (meaning a pledge, security, or payment), which itself came from a Germanic root.
