Na'vi The language of the blue-skinned natives of the planet Pandora. They have 3,429 words for what we call "love," 94 for "carbon trading," 542 for "sister-in-law" and none for "pants." There are several dialects based solely on the noises made when clearing one's throat.
"…" The Na'vi people express their emotions in many ways, such as staying motionless for days on end to make a point, touching rocks and then denying it, and thinking of a number between © and ¡ but refusing to reveal what it is.
