A story from the Bible tells of old Babylon, where the men decided to build a tower that would touch the sky. But God was unhappy, and he made them speak different languages. They couldn’t understand each other, so their dream never came true.
Yet the dream remains alive: if all men speak the same language, they can do anything. L. L. Zamenhof from Poland was among the men who pursue this dream. He developed Esperanto（世界语）between 1877 and 1885.
As the most successful man-made world language, it is spoken by over two million people around the world. Last month, the World Esperanto Congress（大会）, dealing with language rights, ended in Sweden. Most Esperanto speakers are in Central and Eastern Europe and in East Asia, particularly Chinese mainland.
Esperanto has two advantages. First, it’s easy. Each letter has exactly one sound and there are just 16 basic grammar rules. The second advantage is that it belongs to no one country. But Esperanto has only reached a small number of people pared with natural languages widely used around the world---such as English or Chinese. While these languages are deeply connected with their nations and cultures, Esperanto doesn’t have this background.
Will Esperanto really bee a global language? It remains a question.
