Phonology - Cask of Armadillo
PHONOLOGY COMPLETED ON 2/1/2016.

Vowels
MONOPHTHONGS DIPHTHONGS

Phonotactics
Every syllable follows (C)(C)(C)V; all syllables must be open.

The three-consonant cluster in the above phonotactics is only allowed if the last consonant is a liquid / approximate. Otherwise, consonant clusters are limited to two consonants.

Accents
Three independent elements of prosody (here referred to as "accents") are used:  Pitch Accents (tone), Long accents (length), and Dynamic Accents (stress). The default prosodic quality is not considered an "accent", e.g. mid tones, unstressed vowels.
 * Pitch Accents
 * Pitch accent only affect diphthongs, and each diphthong has two possible pitch accents. This language operates on a register tone system, with a phonemic distinction between high, mid, and low, with mid as the default. A word may or may not have any pitch accents, and there is no limit to how many a word may have.
 * Dynamic Accents
 * Dynamic accents affect only monophthongs, and in this category there is only one possible accent. This stress can fall on any syllable in a word, and is phonemic. The default accent for any vowel is unstressed, but there is no default location for the dynamic accent, though every word must possess at least one. There is no limit on how many dynamic accents a word may have, though dynamic accents never occur on consecutive vowels.
 * Long Accents
 * Long accents can affect both monophthongs and diphthongs, and are independent of the other two forms of accent, e.g. a vowel may have both dynamic and long accents. The default quality is a normal length vowel, and there are two accents in this category, long vowels, and very short vowels. Words don't have to include a long accent, but the number of long accents in a word can never exceed one.

Writing System
an apostrophe may be used to separate digraphs. áì (/ai/ low tone) á'ì (/aỹ/)

for long vowels, double the vowel, or the last vowel of a diphthong.

for short vowels use an  at the end of a syllable.
