From Tolkien Gateway
Originally it meant "people", but it was blended and confused with the quite distinct root ndor "dry land" (cf. Sindarin dôr) and the suffix forms -nórë, -ndórë or -dórë are also seen shortened to -or.
- Númenor = Númen(n)órë ("people of the West") and Númendor ("land of the West")
- Valinor = Valinórë (strictly "the people of the Valar") and Valandor ("the land of the Valar")
- Sindarin dôr
