Proto-Elcassa

General information
Proto-Elcassa is the reconstructed version of Elcassa. It was emerged in 1000, and then later than begin to develop to Old Elcassa. Its grammar and phonology featured the following characteristics, no labials, no inflections for tense nor aspect, very limited syllable structure, a plain-aspirated-tenuis stop/affricate distinction and consonant harmony.

Consonants
The tenuis stops might have been ejectives.

Vowels
Proto-Elcassa had vowel harmony; the front vowels /i, y/ cannot exist in the same word as the back vowels /ɯ, u/. The central vowels /ɨ, a/ are transparent.

Consonantal harmony
Proto-Elcassa exhibited consonantal harmony, this is divided into three groups: +tenuis (tenuis consonants), ±tenuis (plain consonants) and -tenuis (aspirated consonants). This phenomena happened to all stops and affricates in suffixes, when following a syllable and its stop/affricate. For example:
