A Noldorin name for the Dark Elves appearing in The Etymologies from the 1930s (Ety/DOƷ), also appearing as Duveledh in the entry for the root ᴹ√MOR (Ety/MOR). The latter may be a mistake since a miswritten “r” might appear as a “v”; another word Durion appears beside Duveledh, which supports it being a misreading for “r”. It is a combination of dûr “dark” and Eledh “Elf”.

A Noldorin name for the Dark Elves appearing in The Etymologies from the 1930s (Ety/DOƷ, MOR), a combination of dûr “dark” and a variant of the agental suffix -(r)on. According to Carl Hostetter and Patrick Wynne, in one entry this form replaced an element duil- which was part of some kind of etymological definition, but the writing is obscured (EtyAC/MOR).
