Which, of course, leads us on to "courtesan"!
Sorry about the length of this quote; but, according to "our friend", google, but for me, most interesting word in it is the plaintive very last one!
"A courtesan was originally a courtier, which means a person who attends the court of a monarch or other powerful person.[1]
In feudal society, the court was the centre of government as well as the residence of the monarch, and social and political life were often completely mixed together. Prior to the Renaissance, courtesans served to convey information untrusted to servants to visiting dignitaries. In Renaissance Europe, courtiers played an extremely important role in upper-class society. As it was customary during this time for royal couples to lead separate lives—commonly marrying simply to preserve bloodlines and to secure political alliances—men and women would often seek gratification and companionship from people living at court. In fact, the verb to court originally meant "to be or reside at court", and later came to mean "to behave as a courtier" and then courtship, or "to pay amorous attention to somebody".[2] The most intimate companion of a ruler was called the favourite.[citation needed]
In Renaissance usage, the Italian word cortigiana, feminine of cortigiano ("courtier") came to refer to a person who attends the court, and then to a well-educated and independent woman, eventually a trained artist or artisan of dance and singing, especially one associated with wealthy, powerful, or upper-class society who provided luxuries and status in exchange for entertainment and companionship.[3] The word was borrowed by English from Italian through the French form "courtisane" during the 16th century, especially associated to the meaning of "donna di palazzo".[1]
A male figure comparable to the courtesan was the Italian cicisbeo, the French chevalier servant, the Spanish cortejo or estrecho. It actually seems that the figure of the chevalier servant (French, literally "serving cavalier", lady's escort) of a married lady was quite common in Europe up to the 18th century.[4]
The courtesans of East Asia, particularly those of the Japanese empire, held a different social role than that of their European counterparts. Examples of Japanese courtesans included the Oiran class, who were more focused on the aspect of entertainment in comparison with European courtesans.[5]
Today, the term courtesan has become a euphemism to designate a comforter, escort, mistress or a prostitute, especially one of dignified etiquette who attracts wealthy, powerful, or influential clients.[why?]"
Dignified etiquette? Really??
