Sekés

Setting and Info
Sekés is meant to be as naturalistic as possible a conlang. It has a bundle of somewhat unusual features (multi-areal affricates, palatal and postalveolar contrasting features, six/seven places of articulation, 9-vowel system) combined with rather commonplace ones (affricates, a pitch accent, split-ergative system and others). It's designed towards realism, fluidity, plausibility and general believability. I plan to make Sekés a language that looks like it could've been plucked off the continents down here.

Note to all greedy idiots from the Germanosphere to which I am related: Hans, no way you stealing this.

Phonology
K'ekköksúkü körffasz

Consonants
1These do not occur outside of sound changes and are not found in native words.

All double consonants (except double " l ") are pronounced as geminate. As an aesthetically more appealing way to write certain geminates, the first consonant of each di/trigraph is doubled (jjy, tts, ppf, qqh)

Vowels
All vowels are monothongs

Phonotactics
The syllable structure of Sekés is a maximal:

"C" represents any non-trill, non-nasal, non-lateral fricative or non-approximant consonant and "N" represents vowels, trills, nasals, lateral fricatives and approximant. Syllables sometimes tend to be "CCV", "CV", "VC" or even just plain "V" and words generally tend to end in a consonant.

Morphophonology, Morphological Sound Changes
Sekés employs multiple regularised, morphological sound changes.

Glottal Reinforcement
Glottal reinforcement is a regular sound change in all words. In vowel-initial words, the vowels are reinforced with an unwritten glottal stop. This process is simmilar to word-initial glottal stops in German.

Regressive Palatalisation
Regressive palatalisation is a regular sound change in which certain consonants move more towards a back place of articulation. It is triggered by " i " and " ü ". The following consonants are palatalised:

Regressive Sibilarisation
Regressive sibilarisation is a regular sound change in which certain consonants sibilise into other consonants when they are followed by "e" or "ö". The following consonants are sibilised:

Crasis
Crasis is (mostly) regular sound change affecting only vowels in which " i " and "u" that came together due to any circumstance phonetically convert to "ü" but are written as so. There are exceptions to crasis but the exceptions have been mostly regularised, too.

Crasis happens both inside a word and at word boundaries and doesn't discriminate between vowel order or any other boundary except that the vowels must have nothing in between them.

A non-crasified vowel combination uses diastresis over " i " (" ï ") and can sometimes be seen in affixes. The so-called uncrasified " i " is phonetically equal to the classic " i " but phonologically behaves differently. The uncrasified version is written only when near "u" and written classically without it.

Gluttural Regressive Voicing
G.Regressive voicing is a regular sound change in which prepalatal/gluttural plosives (k/g/q) turn into reversedly voiced ones (g/k/qg respectively) when preceding an opposite-voiced fricative or plosive. It is either represented orthographically or left out for etymological reasons. It is solely one-level, so a cluster such as "kgp" would turn into "ggp" but not "kkp".
