Germans use the "apostrophe s" .... since we are ... ehem, ... Americanised ("Americanized").
(Thus, making 'of course' even more mistakes. :wink: )
Quotation from about.com:
Quote:It may offer you some comfort to know that even Germans have problems with the genitive. A common error made by native-speakers of German is to use an apostrophe - English-style - in possessive forms. For instance, they will often write "Karl's Buch" instead of the correct form, "Karls Buch." Some observers claim this is an influence of English, but it is an influence that is often seen on store signs and even on the sides of trucks in Austria and Germany.
For non-Germans, there are other genitive
Seriously, generally and grammatically you are correct ... nearly :wink:
Quote:Names add -s (no apostrophe!) in the genitive, regardless of gender or number; if the name already ends in an -s or -z, only an apostrophe is added. Martines Jacke, Hans' Handschuhe, Müllers Auto. Names of people precede the noun possessed, other names typically follow: die Zukunft Europas.
