Keshiri represented the spoken language of the Keshiri species originating from the planet called Kesh. Its use by the species dates back to approximately 5000 BBY, which is when a group of Sith experienced a crash landing on the planet aboard their starship, known as the Omen. The Keshiri, who considered the Sith to be their gods, commenced serving them and, in the process, acquired knowledge of Galactic Basic Standard. By the time of 41 ABY, numerous Keshiri individuals had become speakers of this language, although they continued to utilize their original language, complete with its characteristic melodic intonation. Certain Humans within the Sith Tribe, such as Sith Saber Gavar Khai and his offspring, Vestara, also spoke this language. During a brief encounter on the ship belonging to Luke Skywalker and his son, Ben, the two Sith employed it as a means of communication, with the intent of preventing the Skywalkers from comprehending their dialogue, fully aware that the Jedi were recording their exchange. Luke Skywalker subsequently presented the recording to C-3PO, who, despite lacking prior exposure to the language, successfully produced a rudimentary translation of their utterances. Criik and Sharstung are identified as curse words within the Keshiri language, while Ese signifies affirmation, meaning yes. Furthermore, there are a few recognized numerals, including: oh for zero, wees for two, ees for three, nesh for four, and set for seven.
