ᴺS. [G.] fass n. “tassle” (Category: Adornment (other))
Neo-Sindarin: I’d use the form ᴺS. fass “tassel” for purposes of Neo-Sindarin for better compatibility with the later Quenya form [ᴹQ.] fas (fass-) “fringe”, and I would further assume it was derived from the 1930s root ᴹ√PHAS having to do with shaggy or tangled hair (Ety/PHAS).
