Aradashe has its own unique language, unrelated to any other in the world. It's a very soft-sounding language, with many vowels. Historical writing used ideograms, pictures that represented words. More recently, Aradashe has adopted a syllabic script. Each symbol represents a syllable.

There are many dialects of Aradashean, not necessarily mutually intelligible. There was some foreign influence from the languages of the Awaga settlers, but this has been mostly absorbed into Aradashean to such a degree that it is difficult to trace.
