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.

suku

root. *sweet

The root ᴱ√SUKU⁽²⁾ appeared unglossed in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. suksa “sweet” and ᴱQ. sutya- “sweeten, soothe” (QL/87). A parenthetical comment indicated that ᴱ√ÐUKU might be the true root form. There are no signs of this root in Tolkien’s later writing.

Primitive elvish

lis

root. *sweet, [ᴱ√] sweetness, [ᴹ√] honey

This root was connected to sweet things throughout Tolkien’s life. It appeared as ᴱ√LISI “sweetness” in the Qenya Lexicon of the 1910s with some derivatives of similar meaning as well as others having to do with grace and blessing, such as ᴱQ. lis (list-) “grace, blessing”; Tolkien made it clear that “sweetness” was the root meaning (QL/54-55). In the contemporaneous Gnomish Lexicon the “sweetness” words all began with gl- and “grace” words with l-: G. glais “sweetness”, G. glist “sugar” (GL/39) vs. G. list “grace, favour, kindness”, G. lista- “bless” (GL/54). This connection between √LIS and “grace” survived in Tolkien’s later writing, since he used Q. lissë for “grace” in Quenya prayers of the 1950s (VT43/29; VT44/12).

This root appeared as ᴹ√LIS “honey” in The Etymologies of the 1930s, with Noldorin derivatives still beginning with gl-: ᴹQ. lis vs. N. glî “honey” (Ety/LIS). It appeared as √(G)LIS in “Definitive Linguistic Notes” (DLN) from 1959, still serving as the basis for words for honey and sweetness (PE17/154), though some of the Sindarin “sweet” words began with l- in this document, such as: S. laich “sweet” (PE17/148).

lís

lîs

lís ("lîs")noun "honey", "oblique līr- but usually from stem liss-" (PE17:154). Compare the reading in the Etymologies: lis (liss-, e.g. dat.sg. lissen) (LIS; Tolkien originally wrote lissë, VT45:28)

lís

noun. honey, honey, *sugar, sweetener

A word for “honey” in Definitive Linguistic Notes (DLN) from 1959 given as lîs and derived from the root √(G)LIS (PE17/154); the usual representation of a long vowel in Quenya would be ✱lís. In DLN Tolkien said that it sometimes appeared as līr- in inflections with the usual change of intervocalic *s* to *r*, but that its usual stem form was liss-. Indeed, in The Etymologies of the 1930s this word was ᴹQ. lis “honey” under the root ᴹ√LIS of the same meaning, and its stem form was also liss- as indicated by its [ᴹQ.] genitive lissen (Ety/LIS). Tolkien originally gave the base noun as lisse in The Etymologies, but this was deleted and replaced by lis (EtyAC/LIS). In The Etymologies its Noldorin cognate was N. glî.

Conceptual Development: A likely precursor to this word was ᴱQ. ile “honey” in Early Noldorin Word-lists of the 1920s, cognate to ᴱN. glí “honey” (GL/59).

Neo-Quenya: Since there are other honey-words in Quenya like Q. nehtë, I would use lís (liss-) for sweeteners in general, including both honey and sugar.

melu

honey

#melu noun "honey", isolated from melumatya, q.v. (PE17:68)

melu

noun. honey

A word for “honey” appearing only in the compound Q. melumatya “honey-eating” in notes from 1967 (PE17/68).

Neo-Quenya: For purposes of Neo-Quenya, I recommend using the better-established Q. nehtë for “honey”.

nectë

honey

nectë noun "honey" (LT1:262; Tolkien's later Quenya has lis; otherwise, nectë would have had to become nehtë_, a form appearing in the Etymologies with the meaning "honeycomb" [VT45:38]. However, this word clashes with _nehtë "angle" or "spearhead, gore, wedge, narrow promontory" from later sources [PE17:55, UT:282].)

nehte

nehtë

noun. honey, honey; [ᴹQ.] honeycomb

A noun for “honey” appearing in 1970 green-ink revisions to the Outline of Phonology (OP2) derived from ✶negdē “exudation” based on the root √NEG “ooze, drip” (PE19/91). It was a later iteration of ᴹQ. nehte “honeycomb” in The Etymologies of the 1930s which had essentially the same derivation (EtyAC/NEG). This in turn was a later form of ᴱQ. nekte “honey” from the Qenya Lexicon of the 1910s derived from the early root ᴱ√NEHE having to do with bees and honey (QL/65).

Neo-Quenya: For purposes of Neo-Quenya, I’d use this word only for “honey”. For “honeycomb” I’d use ᴺQ. nehtelë inspired by ᴱQ. nektele “honeycomb” (QL/65)

glî

noun. honey

A word for “honey” in The Etymologies of the 1930s derived from primitive ᴹ✶g-lisi under the root ᴹ√LIS of the same meaning (Ety/LIS).

Conceptual Development: In Early Noldorin Word-lists Tolkien also had ᴱN. glí “honey” (PE13/144), presumably similarly derived from the early root ᴱ√LISI. However, in the Gnomish Lexicon of the 1910s the word for “honey” was G. neglis with an initial element √neg- (GL/59), the Gnomish equivalent of the early root ᴱ√NEHE that was the basis for ᴱQ. nekte “honey” (QL/65). It is possible that the second element of G. neglis was based on ᴱ√LISI and this was carried forward into later “honey” words.
