Etiquette is the set of norms of personal behaviour in polite society, usually occurring in the form of an ethical code of the expected and accepted social behaviours that accord with the conventions and norms observed and practised by a society, a social class, or a social group. In modern English usage, the French word étiquette dates from the year 1750.
In Company Shocked at a Lady Getting up to Ring the Bell (1805) James Gillray caricatured "A widow and her suitors, who seem to have forgotten their manners in the intensity of their admiration."
At the Palace of Versailles, King Louis XIV used complicated étiquette to manage and control his courtiers and their politicking.
In the 18th century, Philip Stanhope, the 4th Earl of Chesterfield, first used the word etiquette to mean "the conventional rules of personal behaviour in polite society." (William Hoare)
In High-Change in Bond Street, – ou – la Politesse du Grande Monde (1796), James Gillray caricatured the lack of etiquette in a group of men who are depicted leering at women and crowding them off the sidewalk.
Body language is a type of communication in which physical behaviors, as opposed to words, are used to express or convey information. Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space. The term body language is usually applied in regard to people but may also be applied to animals. The study of body language is also known as kinesics. Although body language is an important part of communication, most of it happens without conscious awareness.
Two women talking to each other. Notice the woman in blue has an arm next to her body, the other uses hers to gesticulate; both are signs of body language.
