Ad. [ɣ] vanished before a consonants and finally while lengthening the preceding vowel; [VɣC|-Vɣ] > [V̄øC|-V̄ø]
One of two rules in which ✶[ɣ] vanished. Tolkien stated that when [ɣ] was before a consonant or finally, it “became merged with the preceding vowel, which if short was consequently lengthened” (SD/420), so that for example ✶[aɣda] became [āda] and ✶[-aɣ] became [-ā].
