telpë

silver

telpë noun "silver" (in one example with generalized meaning "money", PE14:54), telep- in some compounds like Teleporno; assimilated telem- in Telemnar and the adj. telemna (KYELEP/TELEP, SA:celeb, LT1:255, 268; also tyelpë, telep-, UT:266). The true Quenya descendant of primitive ¤kyelepē is tyelpë, but the Telerin form telpë was more common, "for the Teleri prized silver above gold, and their skill as silversmiths was esteemed even by the Noldor" (UT:266). In various names: Telperion the White Tree of Valinor; Telperien ("Telperiën"), fem. name including telp- "silver" (Appendix A); Telperinquar "Silver-fist, Celebrimbor" (SA:celeb - also Tyelperinquar); Telporno, Teleporno "Silver-high" = Sindarin _Celeborn(Letters:347, UT:266). _It seems that Teleporno is properly Telerin, Quenyarized as Telporno.
