What is the idea behind having three types of articles for nouns in german language? What benefits german speaking people could get from it? What we gonna loose if we simplify all to "the" as the English language did? Can anybody provide an example of using different articles helps understanding better or making communication easier or preventing misunderstanding?
EDIT: If we consider the creation of the articles in german language is the result of the normal procedure of language evolution, what is the reason behind evolving in this direction that we have now three types of articles?
