The root ᴹ√RUK “demon” appeared in The Etymologies of the 1930s with derivatives ᴹQ. rauko and N. rhaug of the same meaning, serving as the basis for N. Balrog (Ety/RUK). In the Qenya Lexicon of the 1910s, similar “demon” words were derived from primitive ᴱ✶ʒǝroukē instead (QL/32). As for √RUK, in the Quendi and Eldar essay of 1959-60 it was glossed “terrible shapes and the fear they inspire”, serving as the basis for both Q. rauko/S. raug “demon” and S. orch “Orc” < ✱urkō or ✱urkā (WJ/389-90, 415); the latter was instead derived from unglossed ᴹ√OROK in The Etymologies of the 1930s along with various other words for “goblin” in multiple Elvish languages (Ety/ÓROK). Primitive (o)rok reappeared in notes probably from the late 1950s denoting “anything that caused fear and/or horror” (MR/413); this might be a transition towards later √RUK “terrible shapes and the fear they inspire”.

thos
root. frighten, terrify; show dread of
In etymological notes from the late 1950s or early 1960s, Tolkien gave √ÞOS “frighten, terrify” as the basis for the final element of S. guruthos, along with other derivatives like OQ. þossë/S. thoss “fear” and OQ. þosta- “put to fright, terrify” (PE17/87). In other notes from this period Tolkien gave √ÞOS “show dread of”, again as the basis for the final element of S. guruthos “shadow of death” (PE17/95). In The Etymologies of the 1930s, the form N. guruthos “fear of death” appeared a marginal notes to the entry for ᴹ√GOS “dread”, indicating the final element of that word was original derived from ᴹ√GOS (EtyAC/GOS); in this instance its initial element “death” was likely N. guruth rather than S. guru.
ñgor
root. dread, terror, fear, horror
This root was connected to fear and dread in Tolkien’s later writing, most notably in S. goroth as an element in S. Gorgoroth “[Valley] of Terror” as the name of a region in Mordor (LotR/401), as well as in S. Ered Gorgoroth “Mountains of Terror” where Ungoliant dwelled (S/95). The root first appeared in its extended form ᴹ√ÑGOROTH “horror” in The Etymologies of the 1930s (Ety/ÑGOROTH) with a variant ÑGOR-OT mentioned in another entry (EtyAC/GOS). The unextended root √ÑGOR was mentioned regularly in Tolkien’s later writings with glosses like “dread” (PE17/113), “terror, dread” (PE17/154), “fear” (PE17/172) and “terror” (PE17/183). It did not necessarily have an entirely negative meaning, however, as its derivative S. gorn given the sense “revered” in (one possible) etymology of S. Aragorn < Ara-ngorn “Revered King” (PE17/113).
A variant root √NGUR “horror” was mentioned in the Quendi and Eldar essay of 1959-60 (WJ/415), but elsewhere √ÑGUR was generally given the sense “death”; see that entry for detail.
gayakā
adjective. *fell, terrible, dire
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”.
tar
root. stand
The root √TAR appeared unglossed in the Quendi and Eldar essay of 1959-60 as the basis for Q. tára “tall, high” (WJ/417), a word that elsewhere was derived from √TĀ/TAƷ “high” (Ety/TĀ; PE17/186). The root √TAR was glossed “stand” along with derivative tāra “tall” in rough notes on the back of a discussion of the comparitive from around 1967 (PE17/186). The past tense for Q. tarne “stood” appears in other notes from this period, along with Q. astarindo, artarindo or astarmo “bystander” (PE17/70-71). √TAR “stand” seems to be a later iteration of ᴹ√THAR “stand” from the Quenya Verbal System of the 1940s; of this earlier root Tolkien said it “is only used [in describing the location of things] — except, of course, with reference to persons or animals when they are noted especially as ‘standing’ (not sitting or lying) — of mountains, high hills, towers, pillars” (PE22/126).
ay(ar)

ras
root. horn, horn; [ᴹ√] stick up
This root first appeared as ᴹ√RAS “stick up (intr.)” in The Etymologies of the 1930s with derivatives like ᴹQ. rasse and N. rhas or rhasg “horn (especially on living animal, but also applied to mountains)” (Ety/RAS; EtyAC/RAS). It reappeared as ᴹ√RASA “stick up” on an rejected page of roots in the Quenya Verbal System from the 1940s (PE22/127). Finally, √RAS “horn” appeared in Common Eldarin: Noun Structure of the early 1950s, but that was merely the last appearance of the root in Tolkien’s published writings. Q. rassë and S. rass “horn” continued to appear regularly as an element in mountain names in the 1950s and 60s.
(ñ)guruk
noun. horror
dirnā

noun. hole
lewek
root. worm
A root glossed “worm” appearing in etymological notes from the late 1950s or early 1960s serving as the basis for Q. leuca and S. lŷg “snake” (PE17/160), words that also appeared in Appendix E to The Lord of the Rings (LotR/1115). A possible precursor to this root is indicated by “snake” words from the Qenya and Gnomish Lexicons of the 1910s: ᴱQ. lin (ling-) and G. ling (QL/54; GL/54), probably derived from ✱ᴱ√LIŊI.
mik
root. pierce
This root appeared in a late etymology of the name S. Maeglin (“Sharp Glance”) as √MIK “pierce”, along with several other derivatives including the word Q. hendumaika “sharp-eye[d]” (WJ/337). In earlier versions of the tales, the name was given as G. Meglin, but this form of the name was not given a derivation until the 1930s, when N. meglin appeared in The Etymologies as an adjectival form of N. megli “bear” (Ety/LIS). The form of this name became Maeglin in Silmarillion drafts from the 1950s and 60s (WJ/122 note §119), though when Tolkien devised its new derivation isn’t clear. The (unglossed) Quenya word Q. maica appeared in the second version Tengwesta Qenderinwa (TQ2) from around 1950, and it may be related to √MIK “pierce”, but without a translation it is hard to be sure.
ndorē
noun. land
ndōro
noun. land
ngur
root. horror
rass
noun. horn
This root first appeared as unglossed ᴱ√TEŘE [TEÐE] in the Qenya Lexicon of the 1910s, with derivatives like ᴱQ. teret “auger, borer, gimlet”, ᴱQ. tereva “piercing, acute, shrill, sharp”, and ᴱQ. teste “worm”; another set of derivatives based on Q. teren “lissom, lithe” were marked by Tolkien with a “?” (QL/91). In the Poetic and Mythological Words of Eldarissa the root teře was glossed “pierce” (PME/91). Possibly related forms in the contemporaneous Gnomish Lexicon include G. tertha- “devour, destroy” and G. tereg “worm”, but if so they may represent a shift of the root from ᴱ√TEÐE >> ✱ᴱ√TERE (GL/70).
Indeed, in The Etymologies of the 1930s the root was given as ᴹ√TER “pierce” with derivatives like ᴹQ. ter/N. trî “through” and ᴹQ. tereva/N. trîw “fine, acute, [N.] very slender” (Ety/TER). As originally written, the root was ᴹ√TERÉW, but Tolkien changed this to ᴹ√TER and added an extended form ᴹ√TERES that was the basis for ᴹQ. terra/N. tess “fine pierced hole” (EtyAC/TER). The root √TER “pierce” appeared again in notes from 1957 on the origin of Q. Vairë “Weaver” as a variant of √THER “sew” (PE17/33). This specific note was marked through, but given Tolkien’s ongoing use of Q. ter “though”, the root √TER probably survived.
