ᴱ√YERE(NE) root. “*iron”
This root appeared in two different forms in in the Qenya Lexicon of the 1910s: as ᴱ√DYEÐE = ‘EÐE equivalent of ᴱQ. anga “iron” (QL/105), and as ERE(N) “iron or steel” = ᴱ√YEREN (QL/36). In the contemporaneous Gnomish Lexicon Tolkien had related forms G. ger “ore, metal” and G. geth “ore of metals (esp. raw iron)” (GL/38); the second of these was deleted, which probably means Tolkien selected ᴱ√YEREN over ᴱ√DYEÐE. In any cases, none of these forms appear in later writings, where Tolkien largely used √ANGA for “iron”.
