root. *iron
Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
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 Tolkien’s later writing he largely used √ANGA for “iron”.
Neo-Eldarin: In a 2024-08-17 post in the Vinyë Lambengolmor Discord Server (VLDS), Luinyelle suggested restoring ᴺQ. yeren “pig iron” with the added meaning “✱ore”, which also implies the preservation of ᴺS. [G.] ger “ore, [unrefined] metal”. Presumably these words would be derived from a Neo-Root ᴺ√GYEREN of similar meaning.
