As it is the case in many places in the universe, people in the Cylinder have taken that peculiar habit to speak. While they do not understand each other anymore than we do elsewhere, they put a lot of work in acting like they do, and a good part in pretending to understand one another, is to speak the same language. This encyclopedia sums up the several variations of languages that exist in the Cylinder, as well as the way they are connected to one another.
