N. Pendrethdulur loc. “Dimrill-stair”
An Elvish name for the Dimrill stair appearing in Lord of the Rings drafts from the 1940s (RS/433). Its initial element is probably a variant of pendrath “stairway” as suggested by Christopher Tolkien, but the meaning of the final element is unclear. Roman Rausch speculated on some possibilities (EE/1.16).
