Proto-East

Classification and Dialects
Proto-East is the ancestor of most of the languages from Jamania to the Atalan Waters. It was spoken around 6-7,000 years ago south of Mt. Isati and east of the Atalan waters. Its hypothetical Urheimat, backed up by the religious theories of the Prolefisians, is the plains and hills around the current city of Tas. Over time, the language split into the current ones spoken today. The migration of speakers caused lexical divergence, morphological change and sound shifts in Proto-East's dialects.

Proto-East had a relatively complex noun declension, differentiating two genders, 7-9 cases and three numbers. Verbs only distinguished between two numbers, two aspects, reflexive and active voice, four moods, and two tenses.

Consonants
Proto-East also had the fricative /ts/ in its inventory.

/s/ world medially was likely voiced, especially due to the fact that it was written sometimes geminated. Other geminated sounds include /n, r, m/.

Proto-East also had a set of syllabic consonants, which were /l, s, m, n/. These will be distinguished with an acute accent (ń).

/q/ could have been a theoretical voiceless labialized aspirated dorsal stop, but was frequent enough and had its own character that suggests otherwise.

Vowels
Proto-East differentiated vowel length.

Phonotactics
Proto-East allows a basic CCVC syllable structure.
 * 1) Onset
 * 2) The first consonant can be syllabic, but it is in accordance with place of articulation. For example, /m/ can be onset if the next consonant is a labial stop, /n/ with coronals, /l/ can be with dorsals or uvulars. Note that if there is a syllabic consonant in an onset cluster, the next part must be a stop, whether it be plain, labialized, aspirated, (un)voiced. /s/ can be in an onset cluster, but it is not syllabic and can only be followed by voiceless stops.
 * 3) The cluster /hw/ is also allowed, as well as any dorsal stop followed by /r/ or /l. The dorsal stop cannot be labialized.
 * 4) Simple onsets (of one consonant) can be any other consonant.
 * 5) Nucleus
 * 6) The nucleus of a syllable can be any vowel or a syllabic consonant. It can only be one if the onset is simple.
 * 7) Coda
 * 8) All consonants are allowed
