Moriquendi "Dark Elves" (SA:mor, WJ:361, 373), Moringotto "Black Foe", Sindarin Morgoth, later name of Melkor. The oldest form is said to have been Moriñgotho (MR:194). In late material, Tolkien is seen to consider both Moringotto and Moricotto _("k") _as the Quenya form of the name Morgoth (VT49:24-25; Moricotto also appears in the ablative, Moricottollo). Morion "the dark one", a title of Morgoth (FS). Morifinwë "dark Finwë", masc. name; he was called Caranthir in Sindarin (short Quenya name Moryo).
