Ordered Structure of the Thesaurus of Word Roots of German Language

The frequency lists of words exist for different languages, where the frequency of occurrence is inversely proportional to the rank of the word. This is called Zipf law. We compiled the frequency list of the roots of German words. 30000 most often used words use about 1800 German roots. In contrast with the words, the functional dependence of the frequency of occurrence for the roots is drastically different it is exponential. About 44 top German roots deviate from this dependence, being used even more often. The observed regular behaviour of roots, together with the results of our previous work, led us to conjecture, that all the word roots are represented at the cortical surface of human brains in a confined area. The position of any root in this patch of neural tissue determines the frequency of use of this root in the everyday speech. Other elements of speech, prefixes, for example, are represented in another patch of cortical tissue. Existing axonal interconnections between these areas determine allowed combinations that is words.
