Etiquette, one aspect of ecorum, is a code that governs the expectations of social behavior, according to the contemporary conventional norm within a society, social class, or group. Usually unwritten, it may be codified in written form. Etiquette usually reflects formulas of conduct in which society or tradition have invested. An etiquette may reflect an underlying ethical code, or in may grow more as a fashion, as in eighteenth century Britain where apparently pointless acts like the manner in which a tea cup was held became associated with the upper class. Like "culture", it is a word that has gradually grown plural, especially in a multi-ethnic society with many clashing expectations. Thus, it is now possible to refer to "an etiquette" or "a culture", realizing that these may not be universal. In Britain, though, the word etiquette has its roots in the eighteenth century, becoming a universal force in the nineteenth century to the extent that it has been described as the one word that aptly describes life during the reign of Queen Victoria .
