Koyanic languages

The Koyanic languages are a language family found throughout the Koyan region of western Fountainhead, with languages spoken in Qnōp', Krobu and Kóty.

Internal Classification
Koyanic is divided into three major branches based on their reflex of the Proto-Koyanic numeral *qx₂əc "one" (Late Proto-Koyanic *qˀác), which demonstrates some characteristic sound changes of each branch and appears in the formation *qx₂əc-kʰə́mə "one-people" which is used as an endonym in several daughter languages.


 * Qak merges the palatals into the velars, merges aspirated and plain plosives.
 * Kát develops Late Proto-Koyanic vowel phonation into tone and shifts the dorsal stops forwards *c *cʰ *k *kʰ *q *qʰ > *t *tʰ *c *cʰ *k *kʰ.
 * Qʼač innovates ejectives from the glottalisation of obstruents, retains voiceless sonorants.
 * Gäj merges the uvulars into the velars and voices the plain plosives *p *t *c *k → *b *d *ɟ *g in certain environments.

The Qʼač and Gäj branches form the Arklobu-Qachkav group by virtue of both being descended from the Proto-Arklobu-Qachkav language, which features the development of a rich inventory of vowel qualities from Late Proto-Koyanic's vowel phonation system. The proposed phylogenetic tree is shown below.
