Most Pa'lowicks were fluent in both Lowickese and Basic.
Lowickese originally had no written form. However, with the introduction of Lowick to the Galactic community, Pa'lowicks had adapted Basic alphabet to create a written form of Lowickese. To the laypeople, it looked like nonsense written in Basic. Ironically, Pa'lowicks usually were literate in Lowickese, but not in Basic.
