Sy Bisti was a trade language used in the so-called Unknown Regions of the galaxy. Some Chiss, including Thrawn and Ar'alani, spoke it. Eli Vanto, whose parents occasionally did business in the Unknown Regions, was also proficient in Sy Bisti, which he regarded as a perfectly well-defined and eminently useful language. Commodore Karyn Faro could also speak Sy Bisti very well, though she was not fluent.
By the time of the Galactic Empire's reign, Sy Bisti was still used but only by lesser known people. Imperial translator droids could not understand it. Sy Bisti could be written by using Bogolan script.

Sy Bisti was first introduced into the Star Wars Legends universe in Outbound Flight, a novel by Timothy Zahn. The trade language was reintroduced to canon in Zahn's later novel, Thrawn, where it played far more notable role than in the previous literature. In an interview published on StarWars.com, Zahn confirmed that he based Sy Bisti on the Zulu language. Like Sy Bisti, Zulu has many multi-syllable words. After finding a word in Zulu, Zahn explained that he would shift all the vowels one vowel over to create a fictional language that was influenced by Zulu.
