Proto-Xās

Setting
Proto-Xās is reconstructed hypothetical ancestor of the three Xahan language families.

Due to the lack of written evidence of Proto-Xās, it has been reconstructed using various methods from both the reconstructed and recorded parts of the "Big Three".

Phonotactics
The basic syllable in Proto-Xās was mainly made up of (C)CNC forms, but the maximum form allowed for:

This structure means that each nucleus must be surrounded by at least one and at most three consonants on either end.

The nucleus could be any of the following:
 * A, Ā, E, Ē, O, Ō, Y, Q

Basic Grammar
Due to the extremely varied nature of its descendants, certain features of Proto-Xās (such as pronouns) could not be fully reconstructed.

Proto-Xās is believed to be deeply ergative, as no marker was reconstructed to belong to a non-ergative alignment.

Nouns
PX. had a mild to medium complexity nominal system, with at least five genders, 9 cases and three numbers. Gender was added as an agglutinative suffix to cases and numbers were added only in the "Template" case postpositions.

Cases
There are 9 cases in PX. They are traditionally ordered as follows:


 * 1) Ablative
 * 2) Ergative
 * 3) Genitive
 * 4) Absolutive
 * 5) Dative
 * 6) Vocative
 * 7) Locative
 * 8) Instrumental
 * 9) "Template"/Postpositional
