A word appearing as ᴱQ. miru “wine” in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s as the basis for the name of the drink of the Valar: ᴱQ. miruvóre (QL/61; PME/61).
Neo-Quenya: In Tolkien’s later writing, the initial element of Q. miruvórë was derived from the Valarin word Val. mirub “wine”, but I think ᴺQ. miru “wine” can also be retained as an adaptation of that Valarin word.
A word appearing as ᴱQ. mirúva “like wine, winy” in the Qenya Lexicon of the 1910s, an adjectival form of ᴱQ. miru “wine” (QL/61).
Neo-Quenya: Since I retain ᴺQ. miru “wine” for purposes of Neo-Quenya, I would retain ᴺQ. mirúva as well.
