The root ᴹ√PHEN first appeared (unglossed) in The Etymologies of the 1930s with derivatives like ᴹQ. fenda “threshold” and N. fenn “threshold, door” (Ety/PHEN). The root √PHEN “door” reappeared in etymological notes from 1959 as the basis for Q. fendë/S. fen “door” (PE17/181). The most notable name associated with this root was S. Fen Hollen “Closed Door” from The Lord of the Rings (LotR/826; RC/550) along with its precursors in LotR drafts: N. Fenn Forn(en) and N. Fenn Uiforn (WR/338, 341).
