When studying vocabulary, I have noticed some variations in the formation of compound nouns:
- Wirtschaft s wunder - an s is added between the two nouns. (Other examples: Alter s gruppe, Abteilung s leiter.)
- Familienbrunch - the singular of the second noun is glued to the plural of the first noun. (Other examples: Stundenplan, Studentenleben, Flötenstunde.)
- Traumberuf - the two nouns are simply brought together. (Other examples: Theaterkarte, Südpol, Südseeinsel, Grußformel.)
and there are probably other patterns I'm missing. I was wondering if there are any (rough?) guidelines for constructing compound nouns; have any regularities been observed? I'd also appreciate a reference, since I don't mind digging deeper into this issue :-)
EDIT: In response to comment; s is not possessive.
