A name that Fëanor gave his youngest son to replace his ominous-sounding mother-name Umbarto (PM/353-4). It is a compound of amba “up” and a masculinized form of the adjective arata “exalted, lofty”, so perhaps meant: “✱High and Lofty” (PM/353). It seems this name was Sindarized as S. Amrod. Conceptual Development: In The Etymologies from the 1930s, the name ᴹQ. Nambarauto “Hammerer of Copper” is given as the Qenya equivalent of his earlier name N. Damrod (Ety/NDAM, RAUTĀ).
