Rackwork → The word is formed from "rack" (from Old English *raca*, meaning a framework or support) and "work" (from Old English *weorc*, meaning activity or labor). The term "rackwork" refers to a structure or framework that supports or holds something, often used in the context of mechanical or architectural designs.
Think of a 'framework' ('rack') that supports 'activity' ('work') — that's what rackwork means.
