Terran

Terran belongs to the Primordial family of tongues. The general survey of the tongues of Erôth gives its usual speakers as earth-based creatures, and holds that it is written as well as spoken.

It is not the tongue of the Terrane, who are a people rather than an element and who speak Jazyk. The two names sit close enough to be taken for one, and often are. Nothing further about Terran was ever written down.
