“An Italian word originating from Baldassare Castiglione’s *The Book of the Courtier*, where it is defined by the author as ‘a certain nonchalance, so as to conceal all art and make whatever one does or says appear to be without effort and almost without any thought about it’.”

Mentioned in Richard Sennett’s book *Together: the rituals, pleasures, and politics of cooperation*, p.117
