ᴺQ. [ᴱQ.] vaina² adj. “clad” (Category: to Clothe, Dress)
An adjective appearing as ᴱQ. vaina in the Gnomish Lexicon of the 1910s as the cognate to G. bain “clad” (GL/21), clearly based on the early root ᴱ√VAẎA “enfold, wind about” as suggested by Christopher Tolkien (LT1A/Vai; QL/100).
Neo-Quenya: Since ᴹ√WAY “enfold” appears in The Etymologies of the 1930s (Ety/WAY), I would retain ᴺQ. vaina “clad” for purposes of Neo-Quenya, especially since it was used in Helge Fauskanger’s Neo-Quenya New Testament (NQNT). It does, however, clash with vaina “blond”.
