númen
west, the way of the sunset
númen noun "west, the way of the sunset" (SA:andúnë, cf. NDŪ, MEN; capitalized Númen under SA:men and in CO), "going down, occudent" (Letters:361), also name of tengwa #17 _(Appendix E). _According to VT45:38, the word is actually cited as "nú-men" in Tolkien's Etymologies manuscript. Allative númenna "Westward" (LR:47, SD:310, VT49:20, capitalized Númenna, VT49:22; numenna with a short u, VT49:23); adj. númenquerna "turned westward" (VT49:18, 20). See also númenyaron, númessier. - In the pre-classical Tengwar system presupposed in the Etymologies, "nú-men" was intended as the name of tengwa #21, to which letter Tolkien at this stage assigned the value n (VT45:38). However, this tengwa was later given the Quenya value r instead and was renamed órë.
