==Phonology==
===Pre-Coelo-Caric===
Based on phonological symmetry and on comparative reconstruction with the Sinushyeinametiniq language, the Proto-Coelo-Caric language was most likely in the middle of the first period of liquid and oral erosion of this phonological system, processes which are characteristic of nearly all stages of the daughter languages.

===Proto-Coelo-Caric===
The changes that the phonology underwent to include tentative phonemes which could have developed after the split analogically affected only the nasal stops, which underwent oralization or Coelo-Caric liquid to become approximants and voiced, possibly nasalized fricatives.

This stage began with the separation of a distinct speech, perhaps while still forming part of the Proto-Indo-European dialect continuum. It contained many innovations that were shared with other Indo-European branches to various degrees, probably through areal contacts, and mutual intelligibility with other dialects would have remained for some time. It was nevertheless on its own path, whether dialect or language.

====Primitive Silōs (PmS)====
This stage began its evolution as a form of [[Centum-satem isogloss|centum]] [[PIE]] that had lost its laryngeals and had five long and six short vowels, as well as one or two overlong vowels. The consonant system was still that of PIE minus palatovelars and laryngeals, but the loss of syllabic resonants already made the language markedly different from PIE proper. Mutual intelligibility might have still existed, but strained, and this period marked the definitive break of Germanic from the other Indo-European languages and the beginning of Germanic proper, containing most of the sound changes that are now held to define this branch distinctively. This stage contained various consonant and vowel shifts, the loss of contrastive accent, and the beginnings of the reduction of unstressed syllables as a result.

====Late Proto-Germanic====
By this stage, Germanic had emerged as a distinctive branch and had undergone many of the sound changes that would make its later descendants recognisable as Germanic languages. It had shifted its consonant inventory from a system rich in plosives to one containing primarily fricatives, had lost the PIE mobile pitch accent in favour of a predictable stress accent, and had merged two of its vowels. The stress accent had also begun to cause the erosion of unstressed syllables already, which would continue in its descendants up to the present day. This final stage of the language included the remaining development until the breakup into dialects, and most notably featured the appearance of nasal vowels and the first beginning of [[Germanic umlaut|umlaut]], another characteristic Germanic feature.

|-
|'''Elimination of {{PIE|/ə/}}''':
* Unstressed {{PIE|/ə/}} is lost between consonants — {{PIE|*sámh₂dʰos}} "sand" > {{PIE|*samədaz}} > {{PIE|*samdaz}}; {{PIE|*takéh₁-}} "to be silent" > (with added suffix) {{PIE|*takəyónti}} "they are silent" > {{PIE|*þagəyanþi}} > {{PIE|*þagyanþi}} > {{PIE|*þagjanþi}}
* {{PIE|/ə/}} > {{PIE|/ɑ/}} elsewhere — {{PIE|*ph₂tḗr}} "father" > {{PIE|*fədēr}} > {{PIE|*fadēr}}; {{PIE|*takéh₁-}} "to be silent" > (with added suffix) {{PIE|*takəyéti}} "(s)he is silent" > {{PIE|*þagəyiþi}} > {{PIE|*þagəiþi}} > {{PIE|*þagaiþi}}

|'''Loss of {{PIE|/t/}}''' after unstressed syllables — {{PIE|*déḱm̥d}} "ten" > {{PIE|*tehunt}} > {{PIE|*tehun}}; {{PIE|*bʰéroyd}} "(s)he would carry, subj." > {{PIE|*berayt}} > {{PIE|*berai}}; {{PIE|*mélid}} ~ {{PIE|*mélit-}} "honey" > {{PIE|*melit}} ~ {{PIE|*melid-}} > {{PIE|*meli}} ~ {{PIE|*melid-}} > {{PIE|*mili}} ~ {{PIE|*milid-}}

|-
|'''[[i-mutation]]''': {{PIE|/e/}} > {{PIE|/i/}} when followed by {{PIE|/i/}} or {{PIE|/j/}} in the same or next syllable — {{PIE|*bʰéreti}} "(s)he is carrying" > {{PIE|*beridi}} > {{PIE|*biridi}}; {{PIE|*médʰyos}} "middle" > {{PIE|*medyaz}} > {{PIE|*midjaz}}; {{PIE|*néwios}} "new" > {{PIE|*newyaz}} > {{PIE|*niwjaz}}
*This eliminates the remaining {{PIE|/ei/}}, changing it to {{PIE|/iː/}} — {{PIE|*deywós}} "god" > {{PIE|*teywaz}} > {{PIE|*Tīwaz}} "[[Týr]]"; {{PIE|*tréyes}} "three" > {{PIE|*þreiz}} > {{PIE|*þrīz}}

|'''{{PIE|/e/}} > {{PIE|/i/}}''' when followed by a syllable-final nasal {{PIE|*en}} "in" > {{PIE|*in}}; {{PIE|*séngʷʰeti}} "(s)he chants" > {{PIE|*sengʷidi}} > {{PIE|*singwidi}} "(s)he sings"
* This followed the earliest contact with Finnic people, since Finnish preserves the older vowel in the loanword ''rengas'' "ring" (from early Proto-Germanic ''*hrengaz'', later ''*hringaz'').

*This followed the earliest contact with the Romans, since Latin Rōmānī was borrowed as *Rūmānīz and then shifted to *Rūmōnīz.
|-
|'''{{PIE|/j/}} is lost between vowels''' except after {{PIE|/i/}} and {{PIE|/w/}} (but it is lost after syllabic {{PIE|/u/}}). The two vowels that come to stand in hiatus then contract to long vowels or diphthongs — {{PIE|*-oyh₁m̥}} "thematic optative 1sg sg." > {{PIE|*-oyum}} > {{PIE|*-ayų}} > {{PIE|*-aų}}; {{PIE|*áyeri}} "in the morning" > {{PIE|*ayiri}} > {{PIE|*airi}} "early"
*This process creates a new {{PIE|/ɑː/}} from earlier {{PIE|/ɑjɑ/}} - {{PIE|*steh₂-}} "to stand" > (with suffix added) {{PIE|*sth₂yónti}} "they stand" > {{PIE|*stayanþi}} > {{PIE|*stānþi}}
|-
|'''{{PIE|/n/}} is lost before {{PIE|/x/}}''', causing [[compensatory lengthening]] and nasalisation of the preceding vowel — {{PIE|*ḱónketi}} "(s)he hangs" > {{PIE|*hanhidi}} (phonetically {{PIE|[ˈxɑ̃ːxiði]}})
