An unglossed root in The Etymologies of the 1930s with derivatives like ᴹQ. ríma “edge, hem, border” and N. rhîf “brink, brim” (Ety/RĪ). Tolkien then added a note “alter to SRI-” without revising the derivatives (EtyAC/RĪ). Given that all its derivatives indicate primitive rīm-, it is almost certainly a later iteration of the unglossed root ᴱ√RIMI from the Qenya Lexicon of the 1910s with derivatives like ᴱQ. rim- “border on, lie at edge, neighbour” and ᴱQ. rímen “border, shore”, given in the same entry with the root ᴱ√RIPI with which it was apparently confused (QL/80). ᴱ√RIMI likewise had derivatives in the contemporaneous Gnomish Lexicon such as G. rim “a stripe, line; border, fringe” (GL/65), though blending with ᴱ√RIPI complicates the analysis; see that entry for further details.

(s)ri
root. *edge, border
reg
root. edge, border, margin
A root in The Etymologies of the 1930s glossed “edge, border, margin” with derivatives like ᴹQ. réna of similar meaning and N. rhain “border” (Ety/REG). ᴹ√REG replaced a rejected variant ᴹ√RAG (EtyAC/REG). The root is evident in only one name: N. {Duil Rain >>} Emyn Rhain “Border Hills” in Lord of the Rings drafts from the 1940s (TI/268, 313), called S. Emyn Muil “Drear Hills” in the published version of The Lord of the Rings (LotR/373; RC/334).

gonod
root. stone
The Elvish words for “stone” were established very early as Q. ondo and S. gond. In the Qenya Lexicon of the 1910s Tolkien gave the root of these words as ᴱ√ONO “hard” with derivatives like ᴱQ. ondo “stone, rock” and ᴱQ. onin “anvil” (QL/70). But its Gnomish derivatives like G. gonn “stone” and G. gontha “pillar” (GL/41) indicate the actual root was ✱ᴱ√ƷONO, since initial ʒ > g in Gnomish.
In The Etymologies of the 1930s Tolkien gave the root as ᴹ√GONOD or √GONDO “stone” with essentially the same Elvish forms: ᴹQ. ondo and N. gonn (Ety/GOND). The root itself did not appear in later writings, but Tolkien continued to state, with great frequency, that the primitive form of the word was ✶gondō (Let/410; PE17/28; PE18/106; PE21/81; PM/374; RC/347).
iw

kaltwa

karan
root. red
This root appeared in The Etymologies of the 1930s glossed “red” (Ety/KARÁN), a later iteration of ᴱ√KṚN of the Qenya Lexicon of the 1910s of the same meaning, but with syllabic ṛ (QL/48). Its main Quenya derivative, Q. carnë, retained the same form throughout Tolkien’s life, but its Gnomish forms G. carn(in) “scarlet” and G. crintha “rosy, pink” (GL/25, 27) became N. caran “red” in the 1930s, and retained that form thereafter.
karani

us
root. [unglossed]
A root in The Etymologies of the 1930s with no glosses or derivatives and no clear function (EtyAC/US).
The root ᴹ√BOR “endure” along with its extended form ᴹ√BORON appeared in The Etymologies of the 1930s along with various derivatives having to do with endurance, faithfulness and everlastingness (Ety/BOR, BORÓN). It was simply a later version of the root ᴱ√VORO from the Qenya Lexicon of the 1910s, unglossed but clearly of a similar meaning based on its Qenya and Gnomish derivatives like ᴱQ. voronda “faithful”, ᴱQ. vorima “everlasting” and G. bron(n) “steadfast, firm” (QL/102; GL/23-24).
Similar forms like Q. voronda or vórima “faithful” continued to appear in Tolkien’s later writing (UT/317). The well established names Q. Voronwë or S. Bronwe(g) “Steadfast, Faithful” retained the same basic form and meaning throughout Tolkien’s life, testifying to the enduring nature of the Elvish root for “endurance”.
