I got confused about the usage of the word. "Von" can be written "Von" if it started in front of the sentence or "v." if abbreviated accroding to The Duden.
What about if you write it in sentences, "when von Bimd walk" or "when Von Bimd walk" I believe the first one is correct and how do you write the initial, is it "v.B" or "vB" as in von Bimd?
