Gwallo

Phonotactics
The basic syllable structure for Gwallo is (C)V(C), but syllables can be much more complex than this. The nucleus of a syllable is a vowel (V), which is mandatory; there are no syllabic consonants. Onsets are always optional, as are codas. The onset may be any consonant (C), but may also be any plosive (excluding palatals) (P) followed by a liquid /l/ or /r/ (L), giving the possible syllables (C)V(C) || (PL)V(C). Additionally, the onset may be the phoneme /ɕ~ʃ/ (S) followed by an unvoiced plosive (T), or the phoneme /s/ followed by /w/ or a fricative, except /ɕ~ʃ/ or /h/ (F). This yields (C)V(C) || (PL)V(C) || (S)(T/F)V(C). The coda may be any nasal (N) or unvoiced plosive (K), but this (K) may be preceded by (L), or by a glide (Y). The Nasal (N) may also be preceded by a glide (Y). Thus the possible syllables in Gwallo are: (C)V(K) || (C)V(L/Y)(K) || (PL)V(K) || (PL)V(L/Y)(K) || (S)(T/F)V(K) || (S)(T/F)V(L/Y)(K) || (C)V(Y)(N) || (PL)V(Y)(N) || (S)(T/F)V(Y)(N).

Sound Changes
Plosives devoice at the end of words, but if and when those words are inflected in such a way that new syllables are added to a word, these devoiced plosives will revert to their original voiced form.

Orthography

 * 1) /θ/ is only used in more remote locations, or by the older generation of speakers. In urban centers and among the young population, it has thoroughly merged with /s/.
 * 2) /v/ is used in foreign words, mostly scientific or educated terms of high prestige from the Kalvatschak Federation. It is also used in some Kannayn loan words for spiritual concepts. /w/ can usually be substituted in both cases, but would not sound as "fancy."
 * 3) Unlike in English and Romance languages on Earth, /c/ and /g/ are never softened before a front vowel.
 * 4) /s/ is pronounced /ɕ~ʃ/ when preceding a plosive, but many (especially younger) speakers actually write this sound with chy; some towns even officially adopted this minor spelling reform into their signage.
 * 5) When /y/ is both preceded and followed by /i/, most speakers will contract this into long /iː/.
 * 6) When /w/ is both preceded and followed by /u/, most speakers will contract this into long /uː/.
