Onset Clusters

The following onset clusters[8] are possible in PIE phonotactics:

Plosive Initial

  • plosive + sonorant
    • e.g. *pro "forward"; *pneu- "breath"; *tjeɡʷ- "revere"; *dleɡʱ- "engage oneself"; *dʱwer- "door"; *ɡʲneh₃- "know"; *kʷrei- "buy"; *ɡʷjeh₃- "live"
  • voiceless labial plosive + voicless coronal plosive
    • e.g. *pter- "wing"
  • voiceless coronal plosive + voiceless dorsal plosive
    • e.g. *tkʲei- "settle"
  • voiceless labial plosive + sibilant + voiceless coronal plosive
    • e.g. *pster- "sneeze"

Sibilant Initial

  • sibilant + sonorant
    • e.g. *sreu- "flow"; *sjuH- "sew"
  • sibilant + plosive
    • e.g. *spend- "pour a libation"; *skʲeh₂i- "shadow"
  • sibilant + postvelar
    • e.g. *sh₂eh₁-i- "bind"
  • sibilant + plosive + sonorant
    • e.g. *splei- "split"; *strenɡ- "squeeze, tie"

Postvelar Initial

  • postvelar + sonorant
    • e.g. *h₁leudʱ- "go"; *h₁jeh₁- "throw"; *h₂wes- "spend the night"; *h₂ner- "man"; *h₃meiɡʲʱ- "urinate"; *h₃reɡʲ- "stretch out the hands"
  • postvelar + plosive
    • e.g. *h₃bʱel- "be of use"
  • postvelar + sibilant
    • e.g. *h₁sih₁- "be" (optative pl. stem)
  • postvelar + sibilant + plosive
    • e.g. *h₂ster- "star"
  • postvelar + sibilant + sonorant
    • e.g. *h₁sjeh₁- "be" (optative sg. stem)

Sonorant Initial

  • labial or labiovelar sonorant + coronal sonorant
    • e.g. *mleuh₂- "speak"; *mreɡʲʱu- "short"; *mneh₂- "be mindful"; *wleikʷ- "flowing, liquid"; *wreh₂d- "branch, root"

Dialectal Developments in Late Proto-Indo-European

The palatovelar plosives merged with the velar plosives:[9]

  • *kʲ, *k > *k
  • *ɡʲ, >
  • *ɡʲʱ, *ɡʱ > *ɡʱ

This removed *kʲ, *ɡʲ and *ɡʲʱ from the phonemic inventory.

Developments in Argument for Italo-Celtic

To do

Developments in Early Proto-Celtic

Following the palatovelar-velar plosive merger, sequences of palatovelar plosives followed by labiovelar semivowels would merge with the labiovelar plosives:[9]

  • *kw (< *kʲw) > *kʷ
  • *ɡw (< *ɡʲw) > *ɡʷ
  • *ɡʱw (< *ɡʲʱw) > *ɡʷʱ

The labiovelar plosives, when followed by a palatal semivowel, became velar plosives:[9]

  • *kʷ > *k /_*j
  • *ɡʷ > /_*j
  • *ɡʷʱ > *ɡʱ /_*j

The labiovelar plosives, when followed by a coronal nasal, became velar plosives:[9]

  • *kʷ > *k /_*n
  • *ɡʷ > /_*n
  • *ɡʷʱ > *ɡʱ /_*n

The labiovelar plosives, when followed by a close back rounded vowel, became velar plosives:[9]

  • *kʷ > *k /_*u
  • *ɡʷ > /_*u
  • *ɡʷʱ > *ɡʱ /_*u

Following the above developments, the voiced labiovelar plosive merged with the voiced labial plosive:[9]

  • *ɡʷ > *b

This removed *ɡʷ from the phonemic inventory.

Then the murmured labiovelar plosive became the Proto-Celtic voiced labiovelar plosive:[9]

  • *ɡʷʱ > *ɡʷ

This removed *ɡʷʱ and returned *ɡʷ to the phonemic inventory.

There were sporadic cases of devoicing plosives in word initial position:[10]

  • *b, *bʱ > *p /#_
  • *d, *dʱ > *t /#_
  • , *ɡʱ > *k /#_
  • *ɡʷ > *kʷ /#_

Lenition: Scenario 1

The remaining murmured plosives merged with their voiced counterparts:[11]

  • *bʱ > *b
  • *dʱ > *d
  • *ɡʱ >

This removed *bʱ, *dʱ and *ɡʱ from the phonemic inventory.

The voiced plosives, in intervocalic environments, underwent allophonic spirantisation:[11]

  • *b > /V_V
  • *d > /V_V
  • > /V_V
  • *ɡʷ > *ɣʷ /V_V

Lenition: Scenario 2

The murmured plosives underwent spirantisation:[10]

  • *bʱ >
  • *dʱ >
  • *ɡʱ >

This removed *bʱ, *dʱ and *ɡʱ from, and added , and to, the phonemic inventory.

These voiced fricatives would then undergo homorganic post-nasal fortition, merging with a voiced plosive:[10]

  • > *b /m_
  • > *d /n_

The voiced plosives, in intervocalic environments, underwent allophonic spirantisation, merging with the voiced fricatives, alongside the addition of a voiced labiovelar fricative:[10]

  • *b > /V_V
  • *d > /V_V
  • > /V_V
  • *ɡʷ > *ɣʷ /V_V

The voiced fricatives, in word initial position, merged with the voiced plosives:[10]

  • > *b /#_
  • > *d /#_
  • > /#_

Then, finally, the voiced fricatives, following liquids, merged with the voiced plosives:[10]

  • > *b /{l, r}_
  • > *d /{l, r}_
  • > /{l, r}_

This removed , and from the phonemic inventory, making them allophones of *b, *d and , alongside *ɣʷ being an allophone of *ɡʷ.

  1. *H covers all potential non-syllabic postvelars.
