The Star Wars space opera universe features some dialogue spoken in fictional languages. The lingua franca of the franchise is known in-universe as "Galactic Basic", used to refer to the language of the film or work itself, be it English or a language that the work was dubbed or translated into. Characters often speak languages other than Basic, notably Shyriiwook spoken by Chewbacca and other Wookiees, droidspeak spoken by R2-D2 and BB-8, Ewokese spoken by Ewoks, and Huttese spoken by Jabba the Hutt. None of these names appear in the Star Wars films themselves.
