Reminds me, I need to work on Starsailor, which is a tonal to the point of being more based on pitch than sound shape. And spoken Darynese -- the written language is pretty well done, but I mention in my notes that the spoken language drops words in favor of body language*.

* Well, except for one dialect, the one spoken by both the in-system colonists and the ones who live orbiting a planet that looks habitable, but is hope to nanomachines (or bacteria -- haven't decided) that kill anything more complicated than the fish dead. Apparently extinct terrestrials can't clean up their messes. Harder to speak with your body in close quarters or in a space suit.
