While browsing hema.nl, I saw “huis en tuin”. Suddenly my subconsciousness popped out a thought: taking into account the difference in meaning, maybe there still is a relation between Dutch “tuin” and English “town”?!
And yes! The article about town on Wikipedia says: “The word town shares an origin with the German word Zaun, the Dutch word tuin, and the Old Norse tun.”
And then: “In English and Dutch, the meaning of the word took on the sense of the space which these fences enclosed.”
