Definition of politesse:
Latin was still the language of diplomacy, to that was added Italian and French; and besides all knightly arts- in so far as they still existed- military drills, and above all, politesse, the new art which rendered men and women more agreeable and obliging in society.- "Pictures of German Life in the XVth XVIth and XVIIth Centuries, Vol. II.", Gustav Freytag.
