Old Shax/Sound Change

Shax, like French, changed significantly from Latin. Here are the sound changes for why:

Sound Changes
V = vowels, C = consonants, V̄ = long vowels, Ć = geminates, P = plosives, L = liquids, Y = glides, S = fricatives, J = palatal values (i, e, j), W = labial values (u, o, w)

 * (ā́, ī́, ū́, ḗ, ṓ) > (ɑ, i, u, ɛ, ɔ)
 * syncope of unstressed vowels except when preceded or followed by two or more conosnants or after an initial consonant
 * ʊ, ɪ > o, e
 * ɑi, oi, au > ɛ, ø, ɔ
 * t, s, m > ∅/_#
 * (a, i, u, ɛ, ɔ, o, e)(m, n) > (ã, ĩ, ũ, ɛ̃, ɔ̃, ĩ, ũ)
