Jawaese was the native language of the Jawa species from Tatooine. It was mainly composed of meaningless syllables, which caused it to fail at being understood. Jawa language is now revised to such a high degree that a Jawa could now fully communicate to others. (Technically this is a modified version of Jawa Trade Language, which doesn't require as much grammar.)
In Jawaese, adjectives come after nouns, as opposed to English where they typically precede nouns. For instance, "Bright sky" might be expressed as "Sky bright" in Jawaese.
