Esperant is a constructed international auxiliary language. It is the most widely spoken constructed language in the world. Its name derives from Doktoro Esperanto ("Esperanto" translates as "one who hopes"), the pseudonym under which physician L. L. Zamenhof published the first book detailing Esperanto, the Unua Libro, on 26 July 1887. Zamenhof's goal was to create an easy-to-learn, politically neutral language that would transcend nationality and foster peace and international understanding between people with different languages.

Although no country has adopted Esperanto officially, Esperanto was recommended by the French Academy of Sciences in 1921 and recognized by UNESCO in 1954, which recommended in 1985 that international non-governmental organizations use Esperanto. Esperanto was the 32nd language accepted as adhering to the "Common European Framework of Reference for Languages" in 2007.
Esperanto is currently the language of instruction of the International Academy of Sciences in San Marino.
Esperanto is seen by many of its speakers as an alternative or addition to the growing use of English throughout the world, offering a language that is easier to learn than English.
