Legwarmer → It is formed from "leg" (from Old English "leg", meaning the limb of the body) and "warmer" (from the verb "warm", meaning to make warm). The word "legwarmer" refers to a garment designed to keep the legs warm.
Think of a 'leg' as the limb that needs to be kept warm, and 'warmer' means to make something warm. So, a legwarmer is something that makes your legs warm.
