A Sindarin name for Q. Valinórë (MR/200). This name is a combination of dôr “land” and the plural Rodyn of Rodon “Vala”, also seen in the Sindarin name for the last day of the Elvish week: Rodyn (LotR/1110). This name may have replaced the earlier name Balannor; see that entry for discussion.

Sindarin name of the “Annals of Valinor”, a combination of ínias “annals” and Dor-Rodyn “✱Land of the Valar” (MR/200).
Conceptual Development: In Silmarillion drafts from the 1930s, this name first appeared as N. Inias Valannor in keeping with the different rules of lenition from that period, later revised to Inias Balannor (LR/202).
A Sindarin term for the Vala (PE17/33), appearing in its plural form S. Rodyn as one of the days of the week (LotR/1110) and also in the Sindarin name for Valinor: Dor-Rodyn (MR/200). It is derived from the prefixal form rod- of raud “noble” (PE17/118, 186). Its final element might be the augmentative suffix -on, perhaps literally meaning “✱Most Noble”. It could also be the agental suffix -on, as suggested by David Salo (GS/283), but that suffix is usually masculine (WJ/400), whereas Rodon seems to apply to all Valar.
