N. Durion pn. “Dark-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).
