Morgoth Bauglir is thus an epithet. His name in Ainulindalë (the creation myth of Middle-earth and first section of The Silmarillion) is Melkor, which means He Who Arises In Might in Quenya. This too is an epithet since he, like all the Ainur, had another true name in Valarin (in the legendarium, the language of the Ainur before the beginning of Time), but this name was not recorded. The Sindarin equivalent of Melkor was Belegûr, but it was never used; instead a deliberately similar name Belegurth, meaning Great Death, was employed.: In earlier versions of Tolkien's legendarium the form of his name was Melko, simply meaning Mighty One.
