As I found out returning from a weekend in Luxembourg, Knapsack is a town in Germany. It’s also a common word for a backpack in English, as in the notorious “knapsack of white privilege“, or the “knapsack problem”. Yet Knapsack is not the word for backpack in German — the modern German word is Rucksack.
So many mysteries: Why is the English word for a kind of backpack, ‘Knapsack’, in reality a German word? When did it first enter English? Did Germans ever use it? If so, why did they abandon it? What is the significance of the fact that there is a town in Germany named Knapsack? Was the Knapsack invented there? Which came first, Knapsack the bag or Knapsack the town?
Anyone have any ideas?
