The alveolar plosives are palatalised to sibilants when adjacent to front vowels on either side. The non-palatalised voiced alveolar plosive is realised as a flap inter-vocalically. The glottal stop is restricted to appearing in absolute-coda and word-initial position in root words, however some compounds do show it intervocalically.
/i ɨ u/
/e ə o/
All vowels may appear as either oral or nasal.
Syllable structure is CV(ʔ). Some parts of the morphology use single-consonant affixes, and some roots show other consonants root-finally - these potential clusters/coda consonants are supported by epenthetic /ɨ/
There is a simple pitch-accent system with three pitch-patterns - first syllable low with rest high, first syllable high with rest low and second syllable high with rest low.
Well it's kinda funky caus there's several things going on.
- Satemisation, with the eventual outcome being /s/ (not merging with original *s, see below)
- The ruki sound change probably happens as well (see "nest") with its eventual outcome being retroflex
- Any remaining PIE *s is debuccalised to /h/ and subsequently lost in many contexts
- Palatalisation of the merged velar series from the velars and labio-velars. This results in the palato-alveolar sibilant
- Cr clusters also turn into the retroflex sibilant
- The stop merger is mostly fairly simple, however with the additional complication that not only did the voiced aspirates become voiceless they must have passed through a stage with strong velar frication, to the point where *dʰ > *tx > *(t)k, with /tk/ being the realisation between vowels, which from the indications of the word list below would likely end up being restricted to verbs and maybe some frozen compounds
- There might be Grassman's Law, but I think I forgot to use it in my last example so I mightn't bother
- The non-high vowels merge as schwa, as do syllabic *r/*l
- Syllabic nasals are turned into nasal ɑ̃, while coda nasals and vowels become long ɑ̃ː
- The glides are lost from merging with all these schwas to create new high vowels (see "wolf", "water", "name" and "three". "root" shows metathesis of the glide and rhotic), and the diphthongs do the same (see "sky")
- *l is lost, with "wheel" and "lake" showing that it may end up as any of /r/, /j/ or zero
- There are also one or two other compensatory lengthenings that happen (see "name")
- The "long schwa" is fronted to /ɛː/
- Stress ends up being mostly word-initial, though a solitary word-initial schwa might be lost if the second vowel of the word is non-schwa (see "horse")
