Chaperone (social)
A chaperone (also spelled chaperon) in its original social usage was a person who for propriety's sake accompanied an unmarried girl in public; usually she was an older married woman, and most commonly the girl's own mother. In modern social usage, a chaperon (frequent in British spelling) or chaperone (usual in American spelling) is a responsible adult who accompanies and supervises young people. By extension, the word chaperone is used in clinical contexts.
