place name. Shadowy Mountains

Earlier name for S. Ered Wethrin from Silmarillion drafts from the 1930s (SM/268, LR/250), a combination of the plural of orod “mountain” (Ety/ÓROT), the lenited plural gwath¹ “shade” (Ety/WATH) and suffix -ion, most likely a genitive plural suffix adapted from the Ilkorin name Urthin Gwethion.
