Even in my youth, I had the idea of constructing a language. Full of stories from Cooper, Gustave Aimard etc, I played American Indians with my friends, and conceived the idea of a special quasi-Indian jargon for our games. It was made of indian words taken from stories, and completed with other necessary words taken from diverse other languages. It had a grammar composed of mixed Ancient Greek and Estonian. This language was never used because my friends refused to learn it.
