Do German and Dutch differ grammatically in any way? - http://www.quora.com/Do-Germ...
Philip Newton German has four noun cases (nominative, genitive, dative, accusative), and while the genitive is wobbling a little in favor of preposition+dative, the system is still pretty robust. Dutch essentially only has one case for nouns, except in certain fixed expressions (such as ‘Koningin der Nederlanden’ with the old genitive). Pronouns still have a subject–object distinction (e.g. ‘ik’/‘mij’). So, pretty much like English in this respect (no cases in nouns, two cases in pronouns). See question on Quora - Meryn Stol
