Sindarin term for a “Man of the West”, the descendants of the Elf-friends of Beleriand and Númenor (LotR/233). This name is a combination of dûn “west” and Adan “Man” (SA/andúnë, adan; PE17/18).
Conceptual Development: In an early version of Glorfindel’s greeting to Aragon, this term was N. Torfir (TI/61), and throughout the Lord of the Rings drafts from the 1940s, the most common term for “High Men” was ᴹQ. Tarkil (TI/84, WR/310). It was not until very late in the drafts that the terms Dúnadan/Dúnedain appeared (WR/363 note #6).
A word for “descent” in notes from 1968 in the name Dúnad in Gyrth “Descent of the Dead” (NM/364). It is clearly based on √NDU “down; descend”.
