Esperanto (help·info) is the most widely spoken constructed international auxiliary language. Its name derives from Doktoro Esperanto, the pseudonym under which L. L. Zamenhof published the first book detailing Esperanto, the Unua Libro, in 1887. The word esperanto means "one who hopes" in the language itself. Zamenhof's goal was to create an easy and flexible language that would serve as a universal second language to foster peace and international understanding. Esperanto has had continuous usage by a community estimated at between 100,000 and 2 million speakers for over a century, and approximately one thousand native speakers. However, no country has adopted the language officially. Today, Esperanto is employed in world travel, correspondence, cultural exchange, conventions, literature, language instruction, television, and radio broadcasting. At least one major search engine, Google, offers searching of Esperanto-related websites via an Esperanto portal.
