Do you think that a universal language will emerge within the next century? English is 51 the lingua franca in many parts of the world, and is the best language currently to know 52 business and science, 53 I don’t think English will 54 become a universal language. I think that if a language becomes the world language, it should be an artificial one. 55 , it might seem to many as an effort to 56 a certain cultural group. The 57 with a universal language is how to 58 it, and how to get the governments of the world to agree 59 its implementation.
If this were to happen, the international language would be the 60 second language of all countries, and legally it would still play second fiddle to the current language of that country. It could allow different tribes in Africa to communicate, or 61 communication between small villages in India that each speaks different languages. Not to 62 it would mean that one would only have to learn two languages no matter 63 in the world he travels.
What 64 specifics—what writing 65 should it use? Where should its words come from? Should the language be highly inflected or very analytical? And furthermore, how will the language be established?
