Esperanto

Esperanto is the most widely spoken constructed international language. The name derives from D-ro Esperanto (Dr. Hopeful), the pseudonym under which L. L. Zamenhof first published the language in 1887. Zamenhof's goal was to create an easy-to-learn and flexible language as a universal second language to foster international understanding.
