In ALL Slavic languages the words for 1&2 rhyme,3&4 rhyme,5&6 rhyme, 7&8 rhyme and 9&10 Rhyme. Is this a mere coincidence or is this an example of BINARY 10011100 computer system first used in basketry & weaving. Is there a mathematical formula which can differentiate between such a random chance and the likelihood that the rhyme was intentional. For decades I have been struggling with this observation. More information at http://www.jandacek.com Ancient Slavic languages and contemporary Slovenian have a DUAL number between singular & plural. Please help. Thank you
