My confusion at the moment lies in the difference in the two prepositions, aus and von. Please note that Dict.cc is my main resource for words and phrases, and it shows the following:
I’m fairly confident in my ability to use these words properly, but sometimes I have used aus when I should have used von and vice-versa. What is the distinction between these two words, and when should one be used over the other?
For example:
Du hast ein Herz aus Gold!
If I hadn’t memorized the fact that aus should be used in that situation, I would have likely used von.
More examples:
Fenster sind nicht aus Metall.
Additionally, the University of Chemnitz’s website shows the following for the two words:
What is the technical, linguistic explanation for using one over the other?
