Cheunh
Cheunh is the official language of the Chiss. It was adopted across Csilla early in Chiss history. Cheunh is a complex, dense tongue that used comparatively few core words and an involved syntax to express ideas; more complicated ideas are expressed by combining related words into a larger whole.
The written form of Cheunh is represented ideographically, and the agglutinative features of the spoken language are reflected in the written form, which combined simpler ideograms to present more complex ideas. The Chiss find the complex nature of their tongue to be a source of pride.
As Humans do not share the same vocal abilities as the Chiss, it is difficult for other species to pronounce it correctly, even after long periods of study. It follows a logical pattern, though, and can be understood after some study.
