Ogili II
Ogili II is a proposed reworking of Ogili to have a shorter list of sound changes that produce nearly the same result, thus enabling the language to more believably be moved further back in time so that its speakers can have intimate contact with Poswobs and Moonshines when those empires were still young.
The language will here below be referred to simply as Ogili.
Phonology
Ogili changed rapidly from an early date. It was spoken by people whose first language was Babakiam, but they soon abandoned Babakiam. Ogili shares very few sound changes with other branches of Khulls or with other surrounding languages, as its people tended to migrate quickly from one area to another.
Changes from Khulls to proto-Ogili
Early on, the ejective consontsn became voiced. Thus /ḳ ṭ ṗ/ > /b d ġ/. Then /z r d/ merged as /d/, which kept [r] as an intervocalic allophone.
The vowel system collapsed to a vertical three-vowel setup, spelt /a e i/ for convenience but pronounced more like [a ɜ ɨ].
Around this time, most fricative consonants became stops or affricates in initial position or after a glottalized tone. Thus, in these positions, /s š ž x g xʷ gʷ/ became /c č ǯ k ġ kʷ ġʷ/. Note that the glottals /ʕ h ʕʷ hʷ/ were excluded from thsi shift.
The lateral approximant /l/ became /ʷ/ after any consonant; that is, it labialized the consonant and then disappeared. This shift did not apply over syllable boundaries, however.
Remaining voiced fricatives were deleted, though their labialization hung around as a new pure /w/ phoneme. Thus /z ž g gʷ ʕ ʕʷ/ became /0 0 0 w 0 w/.
Remaining velar fricatives merged with the glottals. Thus /x xʷ/ became /h hʷ/.
All vowels occurring before a labialized consonant became back rounded vowels, and those that did not were pushed into front unrounded vowels. Thus the inventory of /a ɜ ɨ/ expanded to /a e i/ (front) and /ɔ o u/ (back).
Remaining labialized consonants became pure labials. Thus /pʷ bʷ kʷ ġʷ hʷ/ became /p b p b f/ (note the loss of the other guttural fricatives explained above).
Word-final /l/ disappeared. It had previously been moving towards a [w] sound, but pressure from the existing [w] caused it to disappear instead.
Word-final fricatives became glottal: /f s š h/ all merged as /h/. Note that /f/ is distinct from the others because in an earlier shift it had labialized any vowel occurring before it.
