Esperanto is an artificial language designed to serve internationally as an auxiliary means of communication among speakers of different languages. It was created by Ludwig Lazar Zamenhof, a polish Jewish doctor specialized in eye diseases. Esperanto was first presented in 1887. An international movement was launched to promote its use. Despite arguments and disagreements, the movement has continued to flourish and has members in more than 80 countries. Esperanto is used internationally across language boundaries by at least 1 million people, particularly in specialized fields. It is used in personal contexts, on ’ radio broadcasts and in a number of publications as well as in translations of both modern works and classics. Its popularity has spread form Europe, both east and west, to such countries as Brazil and Japan. It is, however, in China that Esperanto has had its greatest impact. It is taught in universities and used in many translations, often in scientific or technological works. EL POPOLA CHINIO, which means from people’s China, it’s a monthly magazine in Esperanto and it’s read worldwide. Radio Beijing’s Esperanto program is the most popular program in Esperanto in the world. Esperanto vocabulary is drawn primarily from Latin, the Roman’s languages, English and German. Spelling is completely regular. A simple and consistent set of endings indicates grammatical functions of words. Thus for example, every noun ends in "o", every adjective in "a", and basic form of every verb in "i". Esperanto also has a highly productive system of constructing new words from old ones.
