One Chinese Esperanto speaker described Esperanto as a linguistic handshake. When two people shake hands they both reach out halfway. When two people speak Esperanto they have both made the effort to learn a relatively easy, neutral language instead of one person making the huge effort to learn the other person’s difficult national language and the other person making no effort at all except to correct his/her interlocutor’s errors. ~Sylvan Zaft
Esperanto is a constructed language created by L.L. Zamenhof. It's many times easier to learn than any 'natural' language and acts as a bridge of communication between individuals who speak two different native tongues.
