The Deutsches Wörterbuch (The German Dictionary) initiated by Jacob and Wilhelm Grimm already contained over 330,000 headwords in its first edition . The modern German scientific vocabulary is estimated at nine million words and word groups (based on the analysis of 35 million sentences of a corpus in Leipzig, which as of July 2003 included 500 million words in total). </P> <P> The Duden is the de facto official dictionary of the German language, first published by Konrad Duden in 1880 . The Duden is updated regularly, with new editions appearing every four or five years . As of August 2013 it is in its 26th edition and in 12 volumes, each covering different aspects such as loanwords, etymology, pronunciation, synonyms, and so forth . The first of these volumes, Die deutsche Rechtschreibung (English: German Orthography), has long been the prescriptive source for the spelling of German . The Duden has become the bible of the German language, being the definitive set of rules regarding grammar, spelling and usage of German . </P>
