Ancient Quenya Phonetics P32: [ɣ] became [j] between [i], [e] and a vowel

AQ. [ɣ] became [j] between [i], [e] and a vowel; [{ie}ɣV] > [{ie}jV]

Normally any voiced velars spirants ʒ that developed from g eventually vanished, but when it appeared between two e’s it became the semi-vowel y: eʒe [eɣe] > eye [eje]. This combination ultimately became ie. This phonetic development was mentioned in both the Outline of Phonetic Development [OP1] from the 1930s and the Outline of Phonology [OP2] from the 1950s, but the details differed:

Between vowels g > ʒ > y before ē̆ (ei), with the later development as original y (OP1: PE19/32).
After ē̆, ei, ī̆ a development g > ʒ > [ı̯] occurs before a following vowel. But this only produces results of importance in ē̆gē̆ > eı̯e > i(ı̯)e, as tege “line, road” > tie (OP2: PE19/70).

It seems in the 1930s, this sound change was triggered by following e or ei, but in the 1950s, this change was triggered by a preceding e, ei or i. In practice, all the actual examples show both a preceding and following e:

  • tegē [> teʒē > teyē] > Q./ᴹQ. tie “line” (PE19/71; Ety/TEƷ).
  • ᴹ√WEG > ᴹ✶weʒē [> weyē] > ᴹQ. vie “manhood, vigour” (Ety/WEG).

Furthermore, examples involving vowels other than e seem not to demonstrate this sound change:

  • wegō(n) > Q./ᴹQ. veo “living creature; man” and not **vio (PE17/189; Ety/WEG).
  • ᴹ√LUG > ᴹQ. lue “it is heavy, sad” and not **luye (PE22/102).

There is a deleted note in OP2 that indicates a similar change ʒ to w might have occurred between two o’s as well:

Between vowels and ē̆, ei a development g > ʒ > y often occurs; less frequently a development g > ʒ > w before ō̆, ou (OP2: PE19/71 note #15).

One example from The Etymologies of the 1930s seems to demonstrate oʒo > owo > uo:

In later conceptual periods the name Huor was taken from an Atani language, not Elvish (PM/348, 364 note #49), so the above derivation was no longer relevant. The sound change oʒo > owo seems to have been abandoned, though given the lack of examples it is hard to say this for sure.

Conceptual Development: Lack of examples makes it hard to tell if this sound change applied to the Early Qenya of the 1910s and 1920s.
