Mørke sounds like murky.
My Oxford dictionary states that "murk" is probably of Scandinavian origin ("myrkr").
Danish is a Scandinavian language. The words might be related. I don't know.
Both the Scandinavian languages and english are germanic, perhaps the words are just related anyway, even if the vikings didn't bring the word over.
Why it's mørke and not mørkt?
Because bukser is plural
Should really accept trousers as a correct answer for bukser.
For me it has accepted trousers every single time until this one, so that caught me out :(
I was about to write books instead of pants. Phew!
