Root Explanation

Hairspring → The word is formed from "hair" (from Old English *haer*, meaning the fine strands growing from the skin) and "spring" (from Old English *springan*, meaning to leap or jump). A hairspring is a fine spring used in watches that helps regulate time, akin to the delicate nature of hair.

Memory Tip

Think of fine 'strands' ('hair') that 'leap' or 'move' ('spring') to help keep time in a watch.
