Explanation

Five prepositions with the genitive

In standard German, während, wegen, trotz, innerhalb, and außerhalb take the genitive.

Genitive forms

Masculine and neuter use des; feminine and plural use der. Masculine and neuter singular nouns usually add -s or -es: des Plans, des Tages, des Hauses. Feminine and plural nouns normally have no extra ending.

Choose the preposition by meaning: während for simultaneity, wegen for a cause, trotz for a circumstance that does not prevent the result, innerhalb for being inside a limit, and außerhalb for being beyond it. Colloquial German may use the dative after some of these prepositions, but this lesson practises the standard genitive.

With indefinite noun phrases, use eines for masculine/neuter and einer for feminine: innerhalb eines Monats, innerhalb einer Woche.
