Languages of Asdar are largely spoken by humans and humanlikes. Additionaly, scholars can read and write ancient texts which are no longer spoken, including Pensatory Notation which is the writing system for formal, academic magic. Languages of Asdar may also include the languages of intelligent beings in the greater Asdar universe that are conveyed through physical means that do not correspond with the oral apparatus of the humanlike. Many spoken languages can also be recorded by means of a writing system.

Scholars believe all human and humanlike cultures have spoken languages. Scholars have established relationships among the most widely spoken languages. The origin of other languages remains uncertain, such as Neptultchi. The languages of the various Geddamin races have some key similarities not found among other languages and consistent with the titanist theory, all Geddamin languages derive from the ancient Aarokinian Titan language.
