Hessian dialects
South of the Main, the preterite (past tense) is absent and replaced by the perfect (present perfect); north of the Main, on the other hand, preterite forms are common. In the south, standard German is "ich kam", i.e., ich bin kumme, whereas in the north, ich kåm. A second important, albeit Gemeindeutsch difference to standard German is the replacement of the genitive by prepositional and dative periphrases. Thus, instead of "Georg's book" it is "des Buch vum Schorsch" or "em Schorsch soi Buch."
