Languages Exchange As expert said, it seems that thousands of years ago, Iranian people and most of European had been living in north of Russia. Then they immigrated to southern territories. So it is obvious that there are many cognate words in Persian languages and European languages, especially Latin. In addition during three thousand to two thousand years ago there were frequent battles between the Pars Empire and the Roman Empire. I think it had been cause to extensive language exchange between the two countries. My main question is ‘Were there any relationship between European languages and Chinese language in the past?’
