S. #fern n. and adj. “dead” (Category: to Die; Dead; Death)
An adjective in The Etymologies of the 1930s glossed “dead (of mortals)” under the root ᴹ√PHIR “die of natural causes”, used as a plural noun in the name Dor Firn i Guinar “Land of the Dead that Live” (Ety/PHIR). Christopher Tolkien choose to include the name Dor Firn-i-Guinar in the published version of The Silmarillion (S/188), and most Sindarin writers accept its ongoing validity.
