Ilk. [ǣ] became [ē]; [ǣ] > [ē]
This rule was described in the Comparative Tables (PE19/25), but there is only one attested example: ᴹ✶kwǣnē > Ilk. cwên (EtyAC/KWǢ). The same rule applied in “Sindarin” [Beleriandic] development in Tolkien’s linguistic notes from around 1950, but at this later conceptual stage the primitive vowel was [ę̄] (PE18/96).
