√ANGA root. “iron”
The root √ANGA was established as the Primitive Elvish root for “iron” quite early in Tolkien’s writing, with the derivatives Q. anga and S. ang. The form ANGA appeared in the Qenya Lexicon of the 1910s (QL/31) serving as both the root and the Early Qenya form, and G. ang appeared in the contemporaneous Gnomish Lexicon (GL/19). The root ᴹ√ANGĀ reappeared in The Etymologies of the 1930s (Ety/ANGĀ), and it appeared once more in notes associated with The Shibboleth of Fëanor from 1968 (PM/366).

ᴱ√YERE(NE) root. “*iron”
This root appeared in two different forms 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”.
