ᴹ√(N)DAM root. “hammer, beat”
A root in The Etymologies of the 1930s given as ᴹ√NDAM “hammer, beat” (Ety/NDAM), apparently a strengthened form of ᴹ√DAM of similar meaning which was a variant of ᴹ√TAM “knock” (EtyAC/DAM). Its most notable derivative was the N. Damrod “Hammer of Copper” (Ety/NDAM), but in later versions of the Legendarium this character became S. Amrod (PM/353).
