A noun appearing as ᴱQ. vaine “sheath, pod” the Qenya Lexicon of the 1910s under the early root ᴱ√VAẎA “enfold, wind about” (QL/100). It was followed by -o, probably indicating a variant form [vain]o; compare ᴱQ. vainole “quiver”.
Neo-Quenya: I would retain ᴺQ. vainë “sheath, pod” for purposes of Neo-Quenya, based on the later root ᴹ√WAY “enfold” (Ety/WAY).
