Etiquette (/ˈɛtɪkɛt/ and /ˈɛtɪkɪt/; French: [e.ti.kɛt]) is the set of conventional rules of personal behaviour in polite society, usually in the form of an ethical code that delineates the expected and accepted social behaviours that accord with the conventions and norms observed by a society, a social class, or a social group.
