A word for “snake” in the Gnomish Lexicon of the 1910s, along with a deleted variant fenlug (fenlog-) (GL/34), the latter probably a combination with G. lûg “snake”. It was clearly a cognate of ᴱQ. fent “serpent” from the contemporaneous Qenya Lexicon (QL/38).

The word G. iol “lamb” appeared in the Gnomish Lexicon of the 1910s (GL/51), clearly a cognate of ᴱQ. eule of the same meaning from the early root ᴱ√EWE (QL/36), since eu usually became io in Gnomish. G. iolinc “little lamb, lambkin” is a diminutive form (GL/51).
Neo-Sindarin: I would adapt this word as ᴺS. ŷl “lamb” for purposes of Neo-Sindarin, since eu usually became ȳ in Sindarin.
