lammoth

place name. Great Echo

The valley where Morgoth bellowed in pain under the attack of Ungoliant, translated “Great Echo” (S/106), so named because echoes of his cries could still be heard (S/80). It is a combination of lam “echo” with the augmentative suffix -oth. As pointed out by Christoper Tolkien, this name is undoubtedly related to NS. lóm “echo” (SA/lóm).
