The original tongue of the Klatooinians, who were the indigenous inhabitants of Klatooine, was Klatooinian. By the time the Galactic Republic was nearing its end, this language was no longer in active use.
Following the commencement of Klatooinian enslavement to the Hutts around 25,100 BBY, the Klatooinian language gradually faded from memory. In a short time, Klatooinians transitioned to speaking solely Huttese, with the majority becoming unable to read or write. The Klatooinian language persisted solely in old writings, primarily understood by academics who were not Klatooinian. This was quite unusual for Klatooinian culture, which generally placed a high value on maintaining its ancient traditions.
