I've been using various websites and some books at Monash Uni to chase down English words but now I find myself needing to explore several German words. They're probably Middle High German but maybe older.
Two are of particular urgency "zweikampf" and "kampffechter" Both in the sense of a duel or a trial by combat.
Also if anyone knows what a trial by combat was called in C14th Germany that would be helpful.
I've tried the Indo-European Etymological Dictionary but no luck, their server appears to be down.
Any help with the words themselves or a tip on where I should look would be appreciated.
