The Nibiran language was spoken by the Nibirans on the class M planet Nibiru.
The language was very primitive, but it had its own writing system. Some untranslated words spoken by the local people were heard by Captain James T. Kirk and Dr. Leonard McCoy. (Star Trek Into Darkness)
Linguist Marc Okrand invented a Nibiran language. However, some or most parts were ultimately removed from the film. [1]
