Xiri

History
Xiri represents one branch of a small family of languages descended from the Proto-Xiric language, making it a sister language to the other languages of Udovuʼo. The history of Xiri as a distinctly separate language begins some time after 300 BGS and extends throughout the first millennium AGS. Various changes to the language occurred throughout this time, many of which were due to influence from Alöbi. Xiri is typically considered in two major historical stages: Early and Late Xiri, with the historical dialect Exodus Xiri also regarded an important variant.

Early Xiri
The earliest stage of the language which is distinct from its sister languages, spoken from c. 300 BGS until around 100-300 AGS. Canonical Early Xiri is often taken as the state of the language immediately before the first contact with the Alöbi-speaking Öb people, which occurred in the first century AGS.

Late Xiri
After first contact with T'ugü, Xiri underwent some changes which were partially influenced by continued contact throughout most of the Horizon period. The variety of Xiri spoken during this stage of history, primarily 300 - 700 AGS, is Middle Xiri.

Exodus Xiri
Exodus Xiri was a divergent Late Xiri dialect, the particular variant of Xiri spoken by Xiyeru refugees arriving in T'ugü after the Great Sickness in 655 AGS and subsequently throughout the Exodus Period. This stage of the language was strongly influenced by Alöbi and had already begun mixing into what would later become Möxale. Exodus Xiri may have been distinct enough from the contemporary Xiri still spoken in Udovuʼo to consider it a distinct language, and may instead be thought of as a very early stage of Möxale before it had fully matured.

Active sound changes in Early Xiri
These sound changes occurred later in history, changing vocab diachronically and remaining active throughout the Early Xiri period, with newly coined words also exhibiting the changes. This means that an Early Xiri word which had historically undergone alveolar palatalisation, like *nyēre > ñēre, can still undergo glide metathesis: saw-ñēre > sañwēre.
