S. lŷg n. “snake” (Category: Snake)
The best known Sindarin 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), likely from *leukā where the ancient eu became ȳ as was usual in Sindarin (LotR/1115).
