This is a free wikibook on the Lingwa de planeta constructed language or conlang (Lidepla for short).
The authors will be glad to receive some contribution, like your opinion in the talk page, or some improvements of English in the text, or some ideas for exercises.

The book will consist of ten lessons, each containing some grammar explanations, translation exercises, a short text with comments and some useful conversational phrases. You will find some information about one of the languages on which the Lidepla conlang is based and read a fragment of Antoine de St. Exupéry’s The Litte Prince in that language (with transcription). There will also be a wordlist taken from that language.
