The best known Quenya word for “snake”, appearing in Appendix E of The Lord of the Rings (LotR/1115). In 1964 notes on Dalath Dirnen (DD), Tolkien said it was derived from the root √LEWEK “worm” (PE17/160).
nixi
name. fish
A word for “fish” appearing in its plural form lingwi “fish” in notes on The Lands and Beasts of Númenor from 1965 (NM/336) and appearing as ᴹQ. lingwe “fish” from primitive ᴹ✶liñwi under the root ᴹ√LIW in The Etymologies of the 1930s (Ety/LIW).
Conceptual Development: Tolkien had ᴱQ. ingwe “fish” under the early root ᴱ√IWI “fish” in the Qenya Lexicon of the 1910s (QL/43), and this word was also mentioned in the Poetic and Mythological Words of Eldarissa (PME/43). The word {engwe >>} ingwe appeared unglossed in Early Qenya Word-lists of the 1920s (PE16/145). ᴹQ. lingwe “fish” with initial l first emerged in The Etymologies of the 1930s, as noted above.
