The primary language of Star Wars outer rim planet Tatooine, brought in by the Hutt crimelords who control the backwater planet. The actual, functioning language was created by sound technician Ben Burtt, as was the language of the Ewoks. It is the only subtitled language in the Star Wars saga.
A fairly detailed dictionary of Huttese words used to be found here (http://fan.starwars.com/WermosGuide2Huttese/Home.html), until starwars.com discontinued its fan sites, so I'm leaving the old URL up in case someone else finds the page's new location before I do.
