Primitive elvish
tor
root. secrete, hide
ṇ̃kwalē
noun. torment
ekka
noun. hole
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).
angā
noun. iron
rindi
adjective. swift
graw Reconstructed
root. [unglossed], [ᴹ√] dark, swart
This root appeared as a primitive form grawa serving as the basis of the word Q. roa “bear” >> “dog” in notes on monosyllabic roots from 1968 (VT47/35); a Sindarin derivative S. graw “bear” appeared in other notes written around the same time (VT47/12). Patrick Wynne suggested that in the sense “bear” grawa might be connected to the root ᴹ√GRAWA “dark, swart” from The Etymologies of the 1930s (EtyAC/GRAWA).
ambō
noun. hill
barathī
noun. queen
khan
root. brother
A root for “brother” that Tolkien introduced in notes on finger-names from the late 1960s as a companion to √NETH “sister” (VT47/14, 26, 34). It conflicts with, and possibly replaces, earlier uses for √KHAN such as √KHAN “back” in notes from around 1959 serving as the basis for the prefix Q. han- in hanquenta “answer” (PE17/166). The root ᴹ√KHAN also appeared in The Etymologies of the 1930s glossed “understand, comprehend”, with various derivatives in both Quenya and Noldorin of similar meaning (Ety/KHAN).
It is unlikely that all these uses of √KHAN coexisted, but I think at a minimum both √KHAN “brother” and ᴹ√KHAN “understand, comprehend” should be retained for the purposes of Neo-Eldarin, as the latter has no good replacements in Tolkien’s later writing. As for hanquenta “answer”, it might be reinterpreted as “a saying providing understanding”, and so be derived from ᴹ√KHAN “understand”.
lemek
root. [unglossed]
An unglossed root in the Outline of Phonology from the early 1950s illustrating certain phonetic combinations (PE19/98), and therefore possibly not a “real” root.
phut
root. [unglossed]
An unglossed root appearing in the second version of Tengwesta Qenderinwa (TQ2) as an etymological variation of √PUT (PE18/90).
sal
root. [unglossed], *harp(ing), lyre
The unglossed root ᴱ√SALA appeared in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. salma “lyre, small harp” and ᴱQ. salumbe “harping, music” (QL/81). The root √SAL appeared again Common Eldarin: Verb Structure from the early 1950s to illustrate the reformed perfect form of its verb Q. asálie (PE22/132), but since these later forms are unglossed it is unclear whether they have the same meaning (“✱harp(ing)”) as the earlier version of the root.
stuk
root. [unglossed]
taurē
noun. forest
tig
root. [unglossed]
A root appearing in Late Notes on Verb Structure (LVS) from 1969 as the basis for the verb Q. tinga- “go (for a long while)” (PE22/157). The etymology was marked with an “X” and so was probably a transient idea (PE22/157 note #70).
A root appearing in 1964 notes on Dalath Dirnen (DD), with the gloss “secrete, hide” and serving as the basis for S. torn “hidden, secret” and S. torech “secret hole, lair” as in S. Torech Ungol “Shelob’s Lair” (PE17/188). Since this root appears nowhere else with this gloss and S. Torech Ungol has other translations elsewhere, such as “Tunnel of the Spider” (RC/490), I would be cautious about using this root.
