uldor

masculine name. Uldor

Son of the traitorous Easterling chief Ulfang (S/157). This name seems to be Sindarin, and therefore was probably not his true name. It seems to be a combination of [N.] ul- “✱ugly” and -dor “lord”.

Conceptual Development: This character was named N. Uldor in Silmarillion drafts from the 1930s (SM/300, LR/287) and appeared in The Etymologies as a derivative of ᴹ√ULUG (Ety/ÚLUG), the source of the derivation given above.
