Rucksack vs. backpack

[Torsten]

So, what is the difference between a rucksack and backpack? I have the impression "backpack" is more commonly used nowadays but maybe there is more to it?

Hi Torsten

I've heard the rumor that the use of "rucksack" is more common in British English.

I'd say "backpack" is more commonly used in AmE. You might also hear "knapsack".

Hi!

In Germany, at least in that part where I live, "Rucksack" is also used as a term for insidious/malicious people. I wonder whether there is a similar use of the words "backpack" or "knapsack" in the English either at this side of the pond or at the other side?

Hi Michael

No, as far as I know, a backpack is just a backpack and a knapsack is just a knapsack in the US.
