vaita- vb. "to enfold" (VT46:21), "to wrap" (LT1:271). Older (MET) form waita-.
vaiwanoun "wind" (WĀ/WAWA/WAIWA)
vaiya < waiya (also vaia, waia) noun "envelope", especially of the Outer Sea or Air enfolding the world within the Ilurambar or world-walls (WAY, capitalized Vaiya under GEY; the latter entry was struck out). In a "Qenya" text in MC:214, vaiya is simply translated "sky". In the pre-classical Tengwar system presupposed in the Etymologies, vaiya (/ waiya) was also the name of a tengwa letter that does not appear in Tolkien's later table, but which was apparently intended to have the value w > v, like the letter wilya > vilya in the later, canonical system (VT46:21). According to Arden R. Smith, the form of the pre-classical letter is a variant of #21, which letter Tolkien would later call vala(VT46:32).
