"Civility’s defining characteristic is its ties to city and society. The word derives from the Latin civitas, which means city, especially in the sense of civic community,” says author P.M Forni in his book Choosing Civility: The Twenty Five Rules of Considerate Conduct. Another Latin word for city is urbs, which refers to the physical structures or buildings that make up a city. "While buildings and roads make up our physical city or campus, people and relationships make up our community."
