A word in The Etymologies of the 1930s appearing under the root ᴹ√NDŪ “go down, sink, set (of Sun, etc.)” with a hard-to-read gloss (Ety/NDŪ). Superficially, it seems to be a cognate of ᴹQ. númen “western”, but Christopher Tolkien read the gloss as “(?southern)”, though he marked this reading as uncertain. In a discussion on the Lambengolmor mailing list from 2005, Patrick Wynne indicated that the D was capitalized, and the gloss might actually be “✱sunken”, so perhaps being another name for sunken Númenor, based on a later iteration of ᴱN. nuv-/G. num- “sink”.
