A verb appearing as G. faf- “puff, blow, pant” in the Gnomish Lexicon of the 1910s (GL/33). It was perhaps related to the early root ᴱ√FAGA that was the basis for ᴱQ. Fâ = Vilna “lowest air” (QL/37), but GL indicated that G. Fâ was based on a different root than G. faf-.

Neo-Sindarin: For purposes of Neo-Sindarin I would update this verb to ᴺS. faw- “to puff, blow, pant” based on the later root √PHAW “emit”; compare to S. faw that is cognate to Q. föa “breath, puff of breath” (PE17/181). This neologism faw- could be inflected like caw- “to taste” < √KYAW.
