Not much is known about the Japanese language's prehistory, and it is not known when it first appeared in Japan. Chinese documents from the 3rd century AD have recorded a few Japanese words, but texts appeared only after the 8th century. The Chinese language was the major language in Japan during the Heian period. The vocabulary and phonology of Old Japanese are influenced by the Chinese language. Late Middle Japanese is closer to the modern Japanese language. Japanese has a few similarities with the English language.
About Esperanto Language
According to Wikipedia.org, Esperanto is the world's most widely spoken international language. It is created by Polish ophthalmologist L. L. Zamenhof in 1887. The language was created to be used as the universal second language for international communication. Esperanto is spoken in Europe, East Asia, and South America. As a constructed language, Esperanto holds a middle ground between "naturalistic" constructed languages. Esperanto's vocabulary, syntax, and semantics are inspired by the Standard Average European languages. The vocabulary derives from Romance languages and is similar to many Germanic languages. The most notable features of the language are the prefixes and suffixes. The language is easy to adapt roots and can generate words, to make it possible to communicate effectively with a little set of words. Esperanto is the most successful international and has a large population of native speakers.
