when I use Chatterbug for daily words it tests me and an example would be ‘secret’.
If I reply with the answer ‘Geheim’ then Chatterbug marks that as wrong.
If I look up ‘secret’ in the dictionary it comes back with lots of adverbs, and the most popular one seems to be ‘Geheim’. However, the dictionary also has a section marked ‘Substantive’ and that lists ‘Geheimnis’.
I’m wondering what is the difference then, between Geheim and Geheimnis? I think my real question though is a definition for the Substantive.
Many thanks for help in advance.
