Esperanto

Constructed auxiliary language

Esperanto (Esperanto: [espeˈranto]) is the world's most widely spoken constructed auxiliary language. Created by L. L. Zamenhof in 1887 as 'the International Language' (la Lingvo Internacia), it is intended to be a universal second language for international communication. Esperanto culture is grounded in the idea that people can interact on an equal footing across language barriers, without linguistic hierarchies, and with respect for linguistic and cultural diversity.
