ᴺQ. [ᴱQ.] sis- [þiþ-] v. “to scorch, singe, fry” (Category: to Burn, Scorch)
ᴱQ. sisi- v. “to scorch, singe, fry” (Category: to Burn, Scorch)
A verb in the Qenya Lexicon of the 1910s appearing as ᴱQ. sisi- “scorch, singe, fry” derived from the early root ᴱ√SISI “singe, etc.” (QL/84). The root’s likely Gnomish derivatives such as G. thista- “dry up” (GL/73) indicate the root form is probably *ᴱ√ÞISI.
Neo-Quenya: I think this word is worth salvaging as Neo-Quenya ᴺQ. sis-, though it would need to be derived from a Neo-Root ᴺ√THITH to retain this same form.
