Etymology
The word 'chaperon' entered English in the late 14th century from Old French, where it meant "hood, head covering." This French term derived from the Late Latin 'cappa', meaning "cape, hooded cloak." The semantic evolution is a vivid example of metonymy. In medieval times, a noblewoman would wear a distinctive hood or cap, and an older woman who accompanied a young unmarried woman for propriety's sake would also be distinguished by this garment. Over time, the meaning transferred from the protective headgear to the protective person wearing it. By the 18th century, the English meaning had fully settled on the person who provides supervision and protection in social contexts, shedding its original literal sense of a garment.
