Unit 4: Verbs with Prefixes; Adjective Endings
6. Place Names as Adjectives and Nouns
German has a very simple way of using place names as adjectives: add the ending –er. Note that no other adjective endings are added, regardless of case or number.
das Genfer Abkommen | the Geneva Convention |
These adjectives can also be used as nouns:
der Berliner | the Berliner (male from Berlin) |
die Berlinerin | the Berliner (female from Berlin) |
