When can one create a "zusammengesetzes Nomen"? When should one use genitive or prepositions instead?
Long words is one of my favorite features in German. Is there a criterion, *"eine grammatische Empfehlung!*, to know when we can put nouns together?
I'm not talking about creating significant words like "*Glühbirne*" or "*Pusteblumen*", don't even care if they are going to be used. I just want to know when it is correct, and when it is better than using `Genitiv`, prepositions or *Relativsätze* instead.
> 1. *Importbananen* instead of *Bananen zu importieren*, *Bananen, die man importiert*.
2. *Erziehungcampseinrichtung* instead of *Einrichtung der Erziehungcamps* or *Einrichtung von Erziehungcamps*.
Does the answer rely on how often they are going to be used in the text?
**Context:** (*read this text if the question wasn't clear enough.*) I was writing a text, a little essay without other value than exercising German. I had to mention some *"Verhütungsmaßnahmen gegen Jugendkriminalität"*. I have a very good teacher, and she always corrects minimal details and improves sentences whenever there is a better way to write. I was surprised when my word "*Jugendkriminalitätsverhütungsmaßnahme*" was *not* rejected after she read my text. I don't know if she overlooked it, she didn't even understand, or if I was indeed allowed to write that nonexistent word. In any case, I think that the question makes sense.
Would you write what did you mean with "*Jugendkriminalitätsverhütungsmaßnahme*". Do you know that "Verhütungsmassnahmen" means birth control. I think your teacher has overlooked it.
