A hypothetical early root to explain words in the Gnomish Lexicon of the 1910s such as G. fesc “itching, irritating” and G. fesca- “itch, irritate” (GL/34). There are no signs of this root in Tolkien’s later writing, but I think it is worth retaining as a (Sindarin-only) root ᴺ√PHES for purposes of Neo-Eldarin. In earlier versions of Eldamo, I used to recommend using the Neo-Root ᴺ√ITITH for both Neo-Quenya and Neo-Sindarin, but I later decided that if ᴱ√FESE and ᴱ√ITI¹ could coexist in the Gnomish and Qenya of the 1910s, then ᴺ√PHES and ᴺ√ITITH can coexist in Neo-Eldarin as language-specific roots: not every word needs to date back to a shared Primitive Elvish root.
