A Code of Behaviour is a set of rules and guidelines that dictate how people should act in certain situations. ETHICS, which is a 6 letter word, refers to moral principles that govern a person's behaviour or the conducting of an activity. PROTOCOL, which is an 8 letter word, is a system of rules that outline the correct procedures and manners for formal occasions. ETIQUETTE, which is a 9 letter word, is a code of polite behaviour in society or among members of a particular profession or group. Together, these three words describe a Code of Behaviour, which is a set of standards that guide people's behaviour in different contexts.
