Today is the Esperanto day. What is Esperanto? Well I didn't know much until I was contacted by an Esperanto speaker... and a few of my poems got translated from English to Esperanto. Esperanto is the most widely spoken constructed international language. The name derives from Doktoro Esperanto, the pseudonym under which L. L. Zamenhof first published the Unua Libro in 1887. The word itself means 'one who hopes'. Zamenhof's goal was to create an easy and flexible language as a universal second language to foster peace and international understanding.
