4. Shyriiwook is his native language

Those sounds you hear from Chewbacca’s mouth are generated by a combination of noises made by different animals, and you can read about that above. But what’s the name of Wookiee’s language. Shyriiwook (Wookiee Speak or “Wookieespeak“) is the name of Chewbacca’s native language consisting of roars and growls.

Members of other species can understand Shyriiwook, but it cannot be reproduced by others than those who have a Wookiee’s physiology. On the other hand, Wookiees can understand Galactic Basic but due to the structure of their vocal cords they cannot reproduce it.

Han Solo understands Shyriiwook language and Chewbacca understands Han’s language. In the Star Wars novels, Chewbacca builds a Shyriiwook translator in the form of a droid (“Em Teedee“) for his nephew Lowbacca.
