The Sith language was the native language of the people of Ziost and Korriban. It was later expanded upon and evolved when the second generation of Dark Jedi split from the Jedi Order in 7,000 BBY, just after the Battle of Corbos. Even after the extinction of the Sith species, the language was preserved in Sith holocrons, temples, and tomes, and individuals as modern as Vergere, Dr'uun Unnh, and Jerec spoke it.

The Sith language was written in hooked and barbed hieroglyphs. Due to their close connections to the Sith language, they may well have been related to, and possibly even spawned the Massassi language.
