Suaga

Suaga is the language of the Suagir people. It is related to the Daare Karsha family of languages spoken mostly by the peoples of the Kesh Karkhan; scholars believe this is because the Suagirs themselves descend from one (or several) of the many groups dwelling in the deep continental interior, and dwelt there too in the distant past before migrating south to spread out across the steppes at some unrecorded point in time. However, modern Suaga has diverged enough from the Daare Karsha languages that it is distinct from them; a Suaga speaker and a Daare Karsha likely could not make themselves understood to each other.
Suaga is of course spoken as the common language across most of the Suagir steppe, and a dialect is spoken by the inhabitants of the Thyrian steppe as well. Within the Kirdan Empire, some elements of the aristocracy (who are of Suagir or Suagir-Uremite descent) may still speak Suaga, but its predominance has faded since the empire's early day and the use of Tuvai is more common even by the ruling class today. Those who do speak Suaga will have it as a second language along with Tuvai, and will use it to signal pride in their Suagir heritage or an affinity for the ways of their ancestors.
