The Sacred Dragonish

Dragonish is one of the oldest still spoken languages in the world. With only Zaaney Dragonfolks being the only remaining race using it as their native tongue.
Dragonish is considered a classical language, from which the Dalian alphabet and both High Dalenan and modern Naazaa are derived from.
It is also known as the monastic language, as most of the Ancestral Dragon texts are written in Dragonish and all of their priests have been taught to speak and write it.
