Root Explanation

**Jackscrew** → The word is formed from "jack" (from Middle English *jakke*, a term for a device or tool) and "screw" (from Old French *escroue*, meaning a spiral or threaded fastener). A jackscrew is a tool that uses a screw mechanism to lift heavy objects, combining the idea of a lifting device (jack) with a fastening mechanism (screw).

Memory Tip

Think of a 'jack' as a lifting tool and a 'screw' as a threaded fastener — together, they create a device that lifts heavy things.
