feedstock

The compound noun "feedstock" is a modern industrial term, first recorded in the early 20th century. It logically combines the verb "feed," with its Old English roots in nourishment, and the noun "stock," from the Old English concept of a trunk or supply. The term's formation follows a transparent English compounding pattern where "feed" describes the material's function—to be supplied or introduced into a system—and "stock" identifies its nature as a foundational reserve. Thus, the literal "supply to be fed" evolved into the abstract industrial meaning of primary raw material for a manufacturing or chemical process.
