Ilk. voiced stops spirantalized after vowels; [V{bdg}] > [V{vðɣ}]

Ilk. voiced stops spirantalized after vowels; [V{bdg}] > [V{vðɣ}]

In notes for the Comparative Tables, Tolkien said that “in Ilk[orin] ... voiced stops became spirantal medially” (PE19/24), a change that also appeared in the tables themselves (PE19/23). This change was also the rule in Noldorin. From the examples in The Etymologies, it is clear this change occurred consistently after vowels. Some clear examples are: ᴹ✶tubnā > Ilk. tovon (Ety/TUB), ᴹ✶wedā > Ilk. gwedh [gweð] (Ety/WED) and ᴹ✶tūgu > tūgh [tūɣ] > Ilk. (Ety/TUG).

It seems likely that this change occurred before [z] became [i] before voiced stops, since the presence of a primitive [z] in this position meant that a primitive voiced stop was preserved, for example: ᴹ✶mizdē > Ilk. mîd (Ety/MIZD) or ᴹ✶mazgē > Ilk. maig¹ (Ety/MASAG).
