I am having a difficult time trying to find out if spacy lists the gender or for that matter the inflection of any word in German. The software was started in Berlin so I find it very difficult to believe that this would not be the case. When you input the word 'gender' into https://spacy.io/ search box, nothing comes back. When you input the search into google 'gender' site:https://spacy.io/
You actually get back the result that several other languages do have something like gender in their algorithm, for example, Spanish has
ADJ , ADJ__AdpType=Prep , ADJ__AdpType=Preppron|Gender=Masc|Number=Sing , ADJ__AdvType=Tim , ADJ__Degree=Abs|Gender=Fem|Number=Plur
The most detailed info on German at spacy found here https://spacy.io/models/de is very brief with very little info.
When I parse the sentence:
"'Wir glauben, daß diese Vorgänge nur empirisch-psychologisch untersucht werden können und mit Logik wenig zu tun haben.'"
