I'm looking for a very high quality word frequency list in German. This is a list of how often words are used in the German language.
The best one I have found so far is here: 10,000 words. Unfortunately no details are given on the data source.
Does anybody know of anything any better?
If I was to make my own list, can you suggest a good large source of German language text? Something like the The British National Corpus, but in German?
