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.
An adjective form meglin of megli “bear” appearing in The Etymologies of the 1930s (Ety/LIS).
Neo-Sindarin: The sound change dl > gl was not a feature of Sindarin, so most Neo-Sindarin writers adapt this word as ᴺS. medlin “bear-like”, as suggested in HSD (HSD).
