I want to say in German, "the student of Mr. X.".
- I thought I might use the genitive case, and found "des Herrn" in my dictionary, but all the examples containing that phrase referred to God.
- Pages linked from related questions on genitive case do not contain examples with "Herr".
- "der Student von Herrn X" also sounds wrong, but my ears are relatively untrained in German.
How does one say this?
