Quenya name of Celebrimbor appearing as Telpinquar and longer Telperinquar (PE17/42). In the Silmarillion Appendix, Christopher Tolkien gave only longer Telperinquar, which is a more direct equivalent of Celebrimbor (SA/celeb). In private writings Tolkien most often use the (archaic) short form Tyelpinquar (PM/318; VT47/8). As such, this name seems to be a compound of the adjective telpina “like silver” and quár(ë) “fist” (SA/celeb, PE17/42).
Telerin
telperimpar
masculine name. Silver-fist
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). At various points Tolkien imagined his Sindarin name was adapted from his Quenya name T(y)elpinquar or Telperinquar (PE17/42), or the Telerin form of his name Telperimpar (PM/318; VT47/8).
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).
