Check out Moot, the game,

It'll expand your mind. One thing I found fascinating while learning German was the strange way old Nordic words developed into modern cognates. Example: the word moot now means inconsequential or beside the point, but it also means a debate or discussion (Remember the Entmoot in Lord of the Rings?). Before reduced to its modern form, it was "gemot" which gave rise to modern German "gemuetlich" meaning sociable, jovial, friendly. It's also related to meet but not gamut.

Another cognate pair that I always found interesting is German knopf, meaning button, and English knob.
