Ph4 / Esperanto

Esperanto is a language very suitable for international communication.

Free website for learning and studying the international language of Esperanto.
It is also a kind of experiment in teaching methods on the Web — learning a language out of class and without a teacher.

The site has a course for which registration will be required.
The grammar section (Esperanto has a simple and clear grammar).
And a forum where you can find help if something is not clear, and most importantly, start using Esperanto - practice.
