This will be written from the standpoint of a native English speaker who has some familiarity with Spanish and French and a bit more familiarity with Russian, so I may mention similarities and differences between them.
I will add the text of my Esperanto Primer (v2.0) later. You may download it immediately below.
- a printable version of An Esperanto Primer (v2.0)
- Also feel free to download Esperanto USA’s 1 Page Handy-Dandy Esperanto Star-up Kit (PDF) which is a little more comprehensive
- and if that doesn’t sate you then pick up the 16 Rules of Esperanto (PDF)
- an Esperanto Primer (PJB.com.au)
The most useful site (besides this one =) ) I have found to learn Esperanto is Lernu.net.
Other Very Useful Tools:
- A Complete Grammar of Esperanto, The International Language with Graded Exercises for Reading and Translation Together with Full Vocabulary by Ivy Kellerman (at Google Books) or Forgotten Books
- Smart.FM’ Esperanto Flash Cards
- Mazi en Gondolando (a children’s cartoon in Esperanto)
