Zamenhof after with great zeal began for study. He studied English, French, German, Greek and Latin. Based on my knowledge, he concluded that the new language should include suffixes, prefixes and roots of the language they learned, if any person nationality will be able to find in the universal language, something of his own, relatives, friends in their language. Work on the international language, was slow, since by that time already Zamenhof graduated from university and began practicing medicine. In result in the development of a new language was not enough time.
The years passed before work on the grammar of the language and its vocabulary has been completed. Here, a new obstacle. For publishing the book needed the money. Throughout 2 years of Ludwik Zamenhof searching for sponsors to finance his book. And then, finally, he was lucky. Work of interest in his future father-in and gave him money to publish brochures.
So in 1887, saw the light of rather thin book entitled "An international language. Foreword and a complete tutorial. Himself the author of the pseudonym Dr Esperanto. The word "Esperanto" in Zamenhof created the language means "hopeful." This title author gave their language, because the basic idea of its creation was a hope that people all over the world unite by means of international communication. Basis Esperanto alphabet is Latin. But consists of 28 characters: 5 vowels, 2-semivowels and 21 consonant letters and each letter corresponds to one sound. International language grammar is very simple. It includes 16 of the rules, and in them there are no exceptions.
