What is 'ya' in the last letters of countries name?

I believe, though I am not a linguist, that the "ya" sound is a European imposition upon the world, more specifically, one instituted by the Romance Languages, a group which most European languages fit. Austria, for example, in German, is Austereich (though my spelling may be off slightly) meaning either outer empire, or eastern empire, depending on which version of the word ost or oust. The name Ethiopia, also, has European roots, as a mythical country far away, discussed by the Greeks. The modern nation only took the name in the twentieth century. India got it's name from European colonists and invaders, who dubbed the entire sub continent Hindia, for the Indus river, and the people there Hindoos, or Hindus, later to become Indians through the English accent dropping the H from so pronunciation. However, I believe that you make an excellent point about the root of modern languages, as, in most languages world wide, there are similarities. I have heard that the word Mother, and Queen, have a common root word in most languages, and there are other words as well. I too would be very interested to find out more about these seemingly impossible coincidences of Language, both Indo-European, and others. I believe in the 70’s there had been an attempt to “rediscover” the first, universal language, however, I am not sure what the results were. An Archaeology professor had mentioned it off hand, in a lecture I was attending.
