?ᴱ√FASA root. “wash”
A hypothetical early root to explain words in the Gnomish Lexicon of the 1910s such as G. fas- “wash” and G. fôs “bath” (GL/34). It seems to have at least one Qenya derivative as well in the 1910s-name: ᴱQ. Faskala-númen “Bath of the Setting Sun” (LT1/187). There are no signs of this root in Tolkien’s later writing.
