While the "common traders' tongue" is argueably the most common language spoken on Gaeleth, the world hosts a plethora of other languages, from the strange dialects of the Choranil kobolds to a devolved form of Celestial that is used in the theocracy of Nabrol. The languages are optimized for ease-of-use, but sometimes are used multiple times. This list is by no means all-inclusive, and is continually updated as new peoples and races are (re)discovered. Dialects of major language groups are listed in parentheses, with all members of the dialects able to understand the major language group, provided the speaker and the listener are paying attention.
