Avatar: Na'vi, the newest laguage

Na'vi language used in Avatar movie became already widespread at a global level. It is not just a mixture of pretty sounds but a complete language with syntax, grammar and rules. Na'vi - a language particularly invented for the most expensive production in the history of cinematography. How did Na'vi come to life? As part of his scenario for Avatar, James Cameron tried to create a special language supposed to be spoken by Na'vi people living on Pandora planet. For that purpose, Cameron contacted a USC linguistic professor, Paul Frommer - professor of clinical management communication at the University of California's Marshall School of Business. Starting from a few dozens words including characters' names, Frommer's task was to develop an exotic melodious language capable to be spoken by the actors. In the end Na'vi evolved to more than 1000 words containing various properties as ejectives - voiceless consonants pronounced by a few of the world's spoken languages - but also limitations:
"The constrained, of course, is that the language I created had to be spoken by humans" Frommer said. "I could have let my imagination run wild and come up with all sorts of wird sounds , but I was limited by what a human actor could actually do."
