Consonants
Phonology by Kauf The grapheme  is used to indicate palatalization in lieu of a front vowel.

Vowels
There are no diphthongs, only vowel/semivowel combinations.

Any non-palatalized consonant can be labialized, but such a consonant can't be word-final or any part of the cluster.

The vowels [e i] trigger palatalization, except whenever they follow a retroflex, uvular or glottal consonant where they become [ɛ ɨ] (after retroflex) and [æ ɯ] (after uvular and glottal)

The vowel [a] becomes [ɑ] after uvular and glottal consonants, and [æ] after palatal(ized) consonants.

The vowels [o ɔ] become [ø œ] after palatal(ized) consonants, [ʌ ɒ] after uvular and glottal consonants.

Syllable-final nasals cause many vowels to raise [e a o ɔ ø œ] > [ɪ ɜ u o y ʏ]

Most vowel qualities reduce when unstressed & non pre-tonic [i e] > [ɪ] [ɛ æ] > [ɛ] [ɯ a ɑ] > [ә] [o ø] > [ɵ]  [œ ɔ] > [ɞ] [y ʏ u] > [ʉ].

Vowels were lengthened in the open stressed position. Vowel length became phonemic in some dialects when certain consonants dropping also conditioned it.

Stress is mobile & phonemic, similar to Eastern Slavic languages.

Phonotactics
Any onset consists of at least one consonant, this being either a plosive or a non-glottal fricative.

Overall, the syllable structure is (C)(C)CV(C). Three-consonant onsets consist of either two plosives and a liquid or a fricative, plosive, and a liquid. Two-consonant onsets can consist of any two consonants of any type, but these can't be of the same type and PoA.

A coda can consist of any consonant, of any type and PoA.

Roots
The dominating root type in PKR is O-O-C, where O refers to any non-glottal obstruent (ie the only consonants allowed in a simple onset) and C refers to any consonant. The phonetic structure of a root plays a role in determining its declensional paradigm. Some examples include

Nouns
Though there are no formal genders in PKR, nouns decline according to different patterns depending on whether they refer to an inanimate vs living object.

There are three cases in PKR: direct, indirect and dative. Direct functions as either nominative or absolutive and indirect as either accusative or ergative depending on the verb's trigger. Dative has an obvious dative usage that's central to the case, but it also serves as the object of all prepositions. In inanimate nouns the dative and indirect are always identical.

In addition to these cases each noun also features a construct state similar to those found in Semitic languages, which indicates the head of a possessive clause; the dependent is in a different case depending on semantic context (discussed further in syntax.)

Note the following notations:

N= nasal consonant

P= plosive

R= rhotic or approximant

A= a e i o ǫ (basic vowel)

E= e i i o o (raised vowel)

O= ǫ a e ǫ ǫ (lowered vowel)

Á, É, Ó = stressed vowel (note stressed ǫ = ô)

C= consonant (may be a palatalized consonant unless otherwise stated)

Ć= palatalized consonant (note retroflex & glottal -> palatal, uvular does not change)
