S. lhoew n. “poison(ous substance)” (Category: Poison)
Conceptual Development: In The Etymologies of the 1930s Tolkien had N. saew “poison” derived from primitive ᴹ✶sagmā under the root ᴹ√SAG (Ety/SAG). The word saęw “poison” also appeared in The Feanorian Alphabet from the 1930s with the same gloss and basic derivation (PE22/32).
Neo-Sindarin: For purposes of Neo-Sindarin, I would stick to the 1957 word lhoew, used for a specific poison or poisonous substance, as opposed to lhoer for poison in the abstract or poisonousness.
