Gnomish
gwef
noun.louse
A noun appearing as G. gwef “louse” in the Gnomish Lexicon of the 1910s (GL/45), clearly based on the early root ᴱ√GWEVE from the contemporaneous Qenya Lexicon (QL/103).
Neo-Sindarin: I think this word can be salvaged in Neo-Sindarin as ᴺS. gwef “louse” based on the Neo-Root ᴺ√WEB.
