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.
