Aerdi was the language spoken by the Oerid who formed the Great Kingdom. The tremendous reach of that empire in past centuries established the language as the standard communication tool across the Flanaess.

Keoish is the primary language across the Sheldomar Valley, reaching up into Bissel. It is a combination of Oeridian and Suloise languages and is difficult to learn for non-natives. The language is also understood as far east as Greyhawk and Dyvers, and is the main accepted tongue amongst seafarers of the southern waters.

The official tongue of Veluna and Furyondy, Ferrond also is well known westward into Bissel and eastward to Greyhawk and beyond. Related to Aerdi (Common), the language is used across the mid-western Flanaess as a common trading language.

The official tongue of the Baklunish nations of Ekbir, Zeif, Tusmit and Ket, Baklava is spoken by traders that ply the trading routes through Bissel into Ket. Many among the Watchers and Border Companies also speak the Kettish tongue.

This splinter dialect from remote areas of Veluna and Furyondy is related to Ferrond, but is only commonly spoken in backwater areas of these countries.

Demihuman Tongues

Though their clans are scattered across the Flanaess, the length of the elven life means changes to their culture occur very slowly. Although certain distinct dialects have developed since the retreat of the elves from the open lands, elves across the lands are able to easily understand one another in conversation. Celene adheres to the most formal interpretation of the elven language, while those in Highfolk have integrated the most terms from other languages. Other elven communities are usually somewhere between these two extremes.

The racial tongue of the dwarves forms the basis for many localized dialects. Practically every major clan group has modified the language for their own use, although only specific concepts may be difficult to communicate between speakers. In general, the greater the geographical separation of the clans, the further apart their dialects are.

The gnomish language follows a similar path to that of the dwarves, although their dialects tend to include more words of other cultures (particularly elves, dwarves and halflings). Once again, geographical distance increases the difference in dialects.

The halfling language is fairly simple and as such does not change much from one location to another. Some small differences exist due to the incorporation of human, elven or gnomish words (depending on where the halflings live) but these do not present serious troubles to speakers of the language.
