maitë (stem *maiti-, given the primitive form ¤ma3iti) adj. "handed" or "handy, skillful" (VT49:32, 42) in Angamaitë, hyarmaitë, lungumaitë, morimaitë, Telemmaitë, q.v.

anga
iron
anga noun "iron", also name of tengwa #7 (ANGĀ, Appendix E, SA, PM:347, LT1:249, 268). In the pre-classical Tengwar system presupposed in the Etymologies, anga was the name of letter #19, which tengwa Tolkien would later call noldo instead (VT45:6). Masc. names Angamaitë "Iron-handed" (Letters:347), Angaráto "Iron-champion", Sindarin Angrod(SA:ar(a) ). See also Angamando, tornanga and cf. Angainor as the name of the chain with which Melkor was bound (Silm)
anga
noun. iron
This was the Quenya word for “iron” for much of Tolkien’s life, derived from primitive ✶angā of the same meaning (PM/347).
Conceptual Development: ᴱQ. anga “iron” dates back to the Qenya Lexicon of the 1910s (QL/31). In this document it had some competing alternatives: ᴱQ. yere(n) “pig iron” under the early root ᴱ√DYEÐE (QL/105) and {ᴱQ. tongo “iron”} under the early root ᴱ√TOŊO “to hammer” (QL/94), though this second form was deleted. Neither of these alternatives survived in Tolkien’s later writings, and The Etymologies of the 1930s had only ᴹQ. anga “iron” under the root ᴹ√ANGĀ (Ety/ANGĀ). Tolkien stuck with this form thereafter.
erë
iron
erë, eren noun "iron" or "steel"; Eremandu variant of Angamandu (Angband) (LT1:252; "iron" should be anga in LotR-style Quenya, but erë, eren may still be used for "steel". See also yaisa.)
A descendant of Castamir, who warred against Gondor from Umbar in the middle of the Third Age (LotR/1048). The name was also the epessë (adopted name) of Angrod (PM/347). This name is a compound of anga “iron” (PM/347) and maitë “handed” (PE17/162).
Conceptual Development: In the drafts of the Lord of the Rings appendices Castamir’s descendant was named Angomaitë (PM/199) and in the 1st edition of The Lord of the Rings as well, but this was changed in the 2nd edition to Angamaitë (PM/215).
