Last descendant of Fëanor, who crafted the Elvish rings of power (LotR/242), translated “Silver-fist” (PE17/42) or “Silver Grasp” (PM/179). His name is a combination of celebrin “silver” and the suffixal form -bor of paur “fist” (PE17/42, SA/celeb).
Conceptual Development: This name already had its final form when it first appeared in Lord of the Rings drafts from the 1940s (RS/449). The name N. Celebrimbor also appeared in The Etymologies, already with its final meaning (Ety/KWAR).
Quenya name of Celebrimbor, from which his Sindarin name is derived (SA/celeb, PE17/42). In pure Quenya, this name would be ✱Tyelperinquar (not attested). This name also appeared in the shorter form T(y)elpinquar (PM/318; VT47/8, 23). His name is a compound of the adjective telperin “like silver” and quár(ë) “fist” (SA/celeb, PE17/42).
