“The Chiss do not ask to be judged. Not by you; not by anyone.“
Language
The Chiss language is Cheunh and was first accepted during the developing years of their civilization when they formed a planet-wide government which consisted of a single tongue that their society accepted. It is known to be a dense and difficult synthetic language to master as complicated ideas are expressed by uniting unrelated words into larger words. Thus, it has relatively few core words though the syntax requires the speaker to piece together compound words which was complex and involved.
One factor that certainly adds to the complexity of the language was the fact that written Cheunh was not set down in a phonetic alphabet. In writing, Cheunh does not possess an abstract alphabet like Aurebesh with ideograms representing concepts and complex ideas being expressed by combining simpler ideograms. The Chiss hold great pride in not only understanding but conversing in such a language.
The Chiss believe it is quite impossible for non-Chiss to learn to speak it properly. Though this complex, nuance-filled language is difficult for non-Chiss to master due to its intricacies, the Chiss themselves have little trouble mastering Basic. At least some phrases in the language are highly idiomatic.
