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)
