TIL: Zuan isn't a city
https://en.wikipedia.org/wiki/Town#Origin_and_use
The word town shares an origin with the German word Zaun, the Dutch word tuin, and the Old Norse tun. The German word Zaun comes closest to the original meaning of the word: a fence of any material. An early borrowing from Celtic *dunom (cf. Old Irish dun, Welsh din "fortress, fortified place, camp," dinas "city").
