ᴱ√TIFI root. “*flute, hoot”
An unglossed root ᴱ√TIFI appeared in the Qenya Lexicon of the 1910s with derivatives ᴱQ. Timpinen and G. Tinfang (QL/92). These names were translated as “Fluter” in the contemporaneous Gnomish Lexicon along with other derivatives like G. tif- “whistle”, G. timp “hoot, note of a flute”, and G. timpi “a little bell” (GL/70). I think it is worth positing a Neo-Root ᴺ√TIPH “flute, hoot” to salvage some of these early words.
