Númen(n)órënoun "people of the west", confused with Númendor "land of the west" (SA:dôr); hence Númenor as the name of the great isle given to the Edain by the Valar (FS, LR:56); full form Númenórë(LR:47, SD:247, NDŪ); allative númenórenna "to Númenor" (LR:56)
numenda- vb. "get low (of the Sun)" (also númeta-) (LT1:263; in Tolkien's later Quenya núta-)
Númendornoun "land of the west", confused with and replaced by Númen(n)órë "people of the west" (SA:dôr)
númenyaadj. "western" (NDŪ)
númenyaron inflected adj. used as noun?, a word occurring in a phrase from an earlier version of Fíriel's Song, Valion númenyaron, "of the Lords [Valar] of the West". But númenyaron cannot simply mean "of the West"; it seems to be the plural genitive of númenya "western", hence literally *"of the western (things, persons, realms)" or "of the Westerners".
