Geonosian was the language of the Geonosian species native to Geonosis. It consisted of click consonants, possible through the dual mandibles of Geonosians—one moving vertically, and a second, internal set moving horizontally. Aristocrat Geonosians were also able to understand Basic fluently, unlike the lesser castes. It is unknown if they were all physically unable to speak Basic (much like Wookiees), or if they simply preferred their own language. The Queen Karina was known to be capable of speaking Basic. An off-world Geonosian, Tookra, could also speak Basic.
