Which is a set of conventional rules of personal behavior in polite society?
Etiquette is the set of conventional rules of personal behavior in polite society, usually in the form of an ethical code that delineates the expected and accepted social behaviors that accord with the conventions and norms observed by a society, a social class, or a social group. In modern English usage, the French word étiquette (ticket) dates from the year 1750.
In the 18th century, during the Age of Enlightenment, the adoption of etiquette was a self-conscious process for acquiring the conventions of politeness and the normative behaviours (charm, manners, demeanour) which symbolically identified the person as a genteel member of the upper class. To identify with the social élite, the upwardly mobile middle class and the bourgeoisie adopted the behaviours and the artistic preferences of the upper class. To that end, socially ambitious people of the middle classes occupied themselves with learning, knowing, and practising the rules of social etiquette, such as the arts of elegant dress and gracious conversation, when to show emotion, and courtesy with and towards women.
In the 19th century, Victorian era (1837–1901) etiquette had developed into a complicated system of codified behaviours, which governed the range of manners in society — from the proper language, style, and method for writing letters, to correctly using cutlery at table, and to the minute regulation of social relations and personal interactions between men and women and among the social classes.
