We're learning Esperanto in our homeschooling co-op. It's fun! The following is from the booklet we received:
"Esperanto, the international language, is a language developed to make it easier for people of different cultures to communicate. It is now spoken by at least 8.5 million people, in over 100 countries. Esperanto (a planned language) 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." Its simple, logical, regular design makes it easy and fairly quick to learn.
To sign up for the free on-line course and be assigned a personal tutor go here: http://pacujo.net/esperanto/course
Upon completion of the first 10 lessons you will receive a "Certificate of Completion" which in most areas will count for a student's basic language requirements for school graduation.
