In addition the four prepositions "statt" (in place of), "trotz" (in spite of), "während" (during), and "wegen" (because of) which require the genitive in modern formal language, are most commonly used with the dative in colloquial German. For example, "because of the weather" is expressed as "wegen dem Wetter" instead of the formally correct "wegen des Wetters". Other prepositions requiring the genitive in formal language, are combined with "von" ("of") in colloquial style, e.g. "außerhalb vom Garten" instead of "außerhalb des Gartens" ("outside the garden").
