Note 828 — Chapter VIII · MOTTE-CASTLES IN NORTH WALES
Reading edition
The word Din or Dinas, so often used for a fort in Wales, is cognate with the German Zaun, Anglo-Saxon tun, and means a fenced place. Neither it nor the Irish form dun have any connection with the Anglo-Saxon dun, a hill. See J. E. Lloyd, Welsh Place-names, “Y Cymmrodor,” xi., 24.
