My native language is German, so I know what you are saying. Your writing is really very good, and none of us know how long you sit there and look things up.
If I run across something that doesn't make sense, I'll send you a pm.
You may like this little story: A German lady from another forum was invited to a potluck. She didn't know what that meant, so she asked her friend what she should bring. Her friend answered "just bring your favorite dish." She went to the potluck carrying her favorite green plate - empty. She did not know that "dish" means prepared food. She only knew "dish" as the serving plate. She also did not know that a potluck was a food-based get-together where everyone brings their favorite food to share.
