leweg
noun. worm
A word for “worm” in 1964 notes on Dalath Dirnen (DD), a derivative of the root √LEWEK of the same meaning.
Conceptual Development: The Gnomish Lexicon of the 1910s had G. tereg or terch “a worm” (GL/70), likely related to the early root ᴱ√TEÐE “pierce” from the contemporaneous Qenya Lexicon which had a derivative ᴱQ. teste “small worm” (QL/91). The Gnomish Lexicon also had G. gwem “worm” (GL/45), probably derived from ᴱ√GWEVE (QL/103). Early Noldorin Word-lists of the 1920s had ᴱN. lhiw “worm” < ᴱ✶slingwé (PE13/149).
Primitive elvish
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.

Early Quenya
wembe
noun. worm
A noun appearing as ᴱQ. {wembe >>} ’wembe “worm” in the Qenya Lexicon of the 1910s under the early root ᴱ√GWEVE; it had a longer variant *’wembil** (QL/103). Wembe “worm” was also mentioned in the contemporaneous Poetic and Mythological Words of Eldarissa* (PME/103).
Neo-Quenya: Helge Fauskanger adapted this word as ᴺQ. vembë “worm” in his NQNT (NQNT), and I follow his suggestion in part for better compatibility with adapted Gnomish forms from the Neo-Root ᴺ√WEB.

Gnomish
gwem
noun. worm
A noun appearing as G. gwem “worm” in the Gnomish Lexicon of the 1910s (GL/45), probably derived from the early root ᴱ√GWEVE that was the basis for “worm” words in the contemporaneous Qenya Lexicon (QL/103).
Neo-Sindarin: I think this word is worth retaining as (archaic?) ᴺS. gwem “worm” for purposes of Neo-Sindarin as a derivative of the Neo-Root ᴺ√WEB, though I expect the 1964 word S. leweg “worm” is more commonly used.
