There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

A rejected root in The Etymologies of the 1930s for “pale blue” used in an abandoned explanation of N. Eredlindon as “Blue Mountains” (Ety/GLINDI; EtyAC/GLINDI). Later this name was S. Ered Lindon “Mountains of Lindon” (Ety/LIN²; S/123).

liante
noun. spider, spider, [ᴱQ.] tendril, vine
A noun in The Etymologies of the 1930s glossed “spider” derived from the root ᴹ√SLIG with various other derivatives having to do with webs and fine threads (Ety/SLIG). Most notably it was the second element in the name ᴹQ. Ungoliante “Gloomweaver” (LR/230). In the paradigm of The Etymologies, ᴹQ. ungo was “cloud, dark shadow” (Ety/UÑG), not “spider”.
Conceptual Development: In the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s, ᴱQ. liante was glossed “tendril” and was derived from the early root ᴱ√LI+ya “unite many in one” (QL/53, PME/53). In this period it was an element in the name ᴱQ. Ungweliante or Ungwe Lianti “the great spider who enmeshes” (LT1/152), where the intial element ᴱQ. ungwe meant “spider” (QL/98). In the Early Qenya Grammar of the 1920s, ᴱQ. liante was translated “vine” (PE14/55), as opposed to the Qenya Lexicon of the 1910s where ᴱQ. liantasse was “vine” (QL/53).
Neo-Quenya: Tolkien gave no other Quenya words for “spider” in his later writings, but S. ungol was glossed “spider” (Let/180; RC/490, 767) and √ungu- was described as the basis for “spider words” (PE22/160), making it very likely that ✱ungol was “spider” in his later conception of the name Q. Ungoliantë. However, I think [ᴹQ.] liante might be reconceived of as a (feminine?) agental form originally meaning “weaver” or “webspinner”. Furthermore, I think [ᴺQ.] ungol might have come to be associated only with monstrous spiders, the descendants of Ungoliantë, so that [ᴹQ.] liante came to be used of ordinary spiders.

win
root. young, young, [ᴹ√] new, fresh
Tolkien used a similar set of Elvish roots for “youth” and “freshness” for many years. The earliest of these was primitive guı̯u̯ or gu̯iu̯ [ᴱ√GWIWI] in the Gnomish Lexicon of the 1910s with derivatives like G. gui “just, just now, only just, already”, G. guin “recent, fresh”, and G. gwioth “youth” (GL/42). This root reappeared as ᴹ√WIR “new, fresh, young” in The Etymologies of the 1930s with variants ᴹ√WĪ and ᴹ√WIN and derivatives ᴹQ. vírie “youth” and ᴹQ. virya “fresh” (EtyAC/WIR). The ᴹ√WIN variant had derivatives ᴹQ. vinya/N. gwîn “young”. Tolkien considered, but rejected, deriving these from strengthened ᴹ√GWIN instead, producing (also rejected) ᴹQ. winya/N. bîn (EtyAC/GWIN).
Q. vinya appeared in quite a few later names with the gloss “young” or “new”, but the Sindarin form became S. gwain as in S. Narwain “January, ✱(lit.) New Fire” (LotR/1110) and S. Iarwain “Old-young” (LotR/1114; RC/128). In Definitive Linguistic Notes (DLN) from 1959, both were given as derivatives of √WIN “young” along with Q. víne/S. gwîn “youth”, though the Sindarin word for “young” was given as (archaic?) gwein (PE17/191). Also related are various words for “baby” from 1968 notes such Q. †wine/S. gwinig “little-one, baby” (VT48/6). In these notes primitive wini was glossed “little” but this was deleted (VT47/26), making it likely that the earlier senses “young, new” were restored for √WIN.
As for the 1930s root ᴹ√WIR, it might have survived as an element in the month names Q. Víressë/S. Gwirith “April” (LotR/1110), perhaps meaning “✱freshness”.
uñg
root. spider
This root and ones like it were tied to spider words for much of Tolkien’s life, most notably in the name S. Ungoliant and its precursors. The earliest iteration of this root was unglossed ᴱ√GUŊU in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. ungwe/G. gung “spider” (QL/98); Tolkien marked the root with a “?” and given that the Qenya forms had no initial consonant, the actual root may have been ✱ᴱ√ƷUŊU. In The Lost Tales of the 1910s, Tolkien changed G. Gungliont to G. Ungoliont (LT1/156), and in the contemporaneous Gnomish Lexicon the word for “spider” was G. ungwi (GL/75), so it seems Tolkien revised {✱ᴱ√ƷUŊU >>} ✱ᴱ√UŊU.
In The Etymologies of the 1930s, unglossed ᴹ√UÑG had derivatives like ᴹQ. ungwe “gloom” and ᴹQ. ungo “cloud, dark shadow” (Ety/UÑG), and it was the second element ᴹQ. liante in ᴹQ. Ungoliante that meant “spider” (Ety/SLIG). However, in notes from 1969 Tolkien gave ✱ungu- as the basis for “spider” words (PE22/160), as reflected in Q. ungwë “spider’s web” (LotR/1122) and S. ungol “spider” in his later writings (Let/180; RC/490, 767).

spider
liantë (1) noun "spider" (SLIG), in earlier sources ascribed other meanings:(2)liantë "tendril" (LT1:271) and (3) "vine" (PE14:55, cf. liantassë elsewhere)
nessa
young
nessa adj. "young" (NETH), alsoNessa as name of a Valië, the spouse of Tulkas (adopted and adapted from Valarin, or an archaic Elvish formation: WJ:404 vs. 416). Also called Indis, "bride" (NETH, NI1). The fem. name Nessanië (UT:210) would seem to incorporate Nessa's name; the second element could mean "tear" (nië), but since Nessa is not normally associated with sorrow, this #nië is perhaps rather a variant of ní "female" (compare Tintanië as a variant of Tintallë).
tur-
verb. to master, conquer, dominate, win, to master, conquer, dominate, win; [ᴹQ.] to control, govern, *rule; to wield; [ᴱQ.] can, to be able
vinimo
noun. baby, little-one
A word appearing as winimo “baby” (VT47/10) or “little-one, baby” (VT48/6) in notes associated with Elvish Hands, Fingers and Numerals from the late 1960s, in one place with the variant win(i)ke (VT48/6). It was an elaboration of winë (wini-) of similar meaning. Tolkien said that “Pengoloð gives these in archaic Quenya form before the change of w, in most situations to v” (VT48/6), so the modern spelling and pronunciation of this word would be vinimo.
vinya
young
vinya (1) adj. "young" (VT46:22, VT47:26, PE17:191) or "new" (cf. compounds Vinyamar, Vinyarië below; cf. also winya "new, fresh, young" in a deleted entry in the Etymologies, VT45:16; there the word was first written as vinya.) Vinya "the Young", original name of the isle of Númenor among its own people (SD:332).

thlingril
noun. spider
thlingril
noun. spider
A noun appearing as N. thlingril “spider” in The Etymologies, probably a feminine form of N. thling “spider, spider’s web, cobweb” (Ety/SLIG). Christopher Tolkien said the r was uncertain.
Neo-Sindarin: Since initial *sl-* became *lh-* in Sindarin, most Neo-Sindarin writers adapt this word as ᴺS. lhingril, as suggested in HSD (HSD). This word is somewhat questionable, since in later writings √ungu- was the basis for spider words (PE22/160). I think ᴹ√SLIG may be reinterpreted as having to do with threads, and as such I think ᴺS. lhingril can be retained as originally meaning “(female) web spinner”. However, I recommend later S. ungol as the more common Sindarin word for “spider”.

ungol
noun. spider
The Sindarin word for “spider” (Let/180; RC/490, 767), derived from √ungu- that was the basis for spider words (PE22/160).
Conceptual Development: The Gnomish word for “spider” was initially G. gung in both the Qenya Lexicon and Gnomish Lexicon of the 1910s as a derivative of the early root ᴱ√GUŊU (QL/98; GL/43), also appearing an element in G. Gungliont, the earliest name of Ungoliant (LT1/160). In the Gnomish Lexicon the word gung was crossed through, but may have become ging in G. gwidh-a-ging “cobweb” (GL/46). Regardless, Tolkien added G. ungwi “spider” in pencil to the Gnomish Lexicon (GL/75), which seems to indicate a change of the root from ᴱ√GUŊU to ᴱ√UŊU, consistent with the replacement name G. Ungoliont from the contemporaneous narratives (LT1/152).
In The Etymologies of the 1930s, “spider” words were derived from the root ᴹ√SLIG (Ety/SLIG); see N. thling for discussion. Tolkien soon restored Ung-, however, since N. ungol was translated as “spider” in Lord of the Rings drafts of the 1940s (WR/202).

ungol
spider
(pl. yngyl); coll. pl. ?unglath or ungolath
A noun for “spider” in the Gnomish Lexicon of the 1910s with variants cing and cingwin (GL/26). Tolkien indicated this word was related to G. cang “tangled” (GL/25), which was probably based on the early root ᴱ√KAŊA “weave, twine” (QL/45, 98). The i in cing indicates the primitive form was probably kŋ̣g-, since short syllabic nasals became *in* in Gnomish.
