The LADIES' and Gentlemen's Books of Etiquette and Manual of Politeness

Etiquette is a code of behavior that delineates expectations for social behavior according to contemporary conventional norms within a society, social class, or group.
The French word étiquette, literally signifying a tag or label, was used in a modern sense in English around 1750. From the 1500s through the early 1900s, children learned etiquette at school. Etiquette has changed and evolved over the years.
