The eleventh line of Tolkien’s Quenya translation of the Litany of Loreto prayer (VT44/12). The first word is aina “holy” followed by Eruontarië, a name of Mary as the genetrix (female begetter) of God. As pointed out by Wynne, Smith and Hostetter, this word is used to translate Latin “genetrix”, where as Latin “mater” is translated by amil(lë) (VT44/8).
Decomposition: Broken into its constituent elements, this phrase would be:
> Aina Eruontarië = “✱Holy God-genetrix”
aina (2) adj "holy" (AYAN), derived from Ainu. Adopted and adapted from Valarin. According to VT43:32, the word is "obsolete, except in Ainur", apparently suggesting that airë or airëa (q.v.) was the normal term for "holy" in later Quenya. However, Tolkien repeatedly used aina in his translation of the Litany of Loreto: Aina Fairë "Holy Spirit", Aina Neldië "Holy Trinity", Aina Maria "Holy Mary", Aina Wendë "Holy Virgin". He also used Aina Eruontari for "holy Mother" in his rendering of the Sub Tuum Praesidium(WJ:399, FS, SA, VT43:32, VT44:5, 12, 17-18)
