Esperanto
Once upon a time, I took a ten-lesson Esperanto course. The first lesson begins with
Esperanto, the international language, is a language developed to make it easier for people of different cultures to communicate. Its author, Dr. L. L. Zamenhof (1859-1917), published his "Lingvo Internacia" in 1887 under the pseudonym "Dr. Esperanto". It is now spoken by at least two million people, in over 100 countries. There are thousands of books and over 100 periodicals published currently. But what makes it any more international than French, English or Russian?
Incorrectly termed 'artificial' (the right word is 'planned'), Esperanto is specifically intended for international/intercultural use, so those who use it meet each other on an equal footing, since neither is using his or her native language.

Thanks to its simple, logical, regular design, anyone can learn Esperanto fairly rapidly.
