The language is still in development. So far, there is a ~500 word Na'vi-to-English dictionary, the basics of speaking/pronouncing Na'vi, and an in-progress grammar and syntax section.
'Palestinian activists dressed as Na'vi characters from the movie 阿凡达 marched in the village of Bilin to protest the Israeli 墙 of Shame built to 分裂, 拆分 the occupied West Bank.' WOW to how 阿凡达 impacts... O_o
