A noun appearing as ᴱQ. sult (sulp-) “a sip, taste” in the Qenya Lexicon of the 1910s under the early root ᴱ√SḶPḶ (QL/84).
Neo-Quenya: I’d adapt this noun as ᴺQ. salpë “sip” for purposes of Neo-Quenya, from the later form of the root: ᴹ√SALAP (Ety/SÁLAP).
A word appearing as ᴱQ. taste “fringe” in the Qenya Lexicon of the 1910s under the early root ᴱ√TASA (QL/89). 1940s ᴹQ. atsa “tassel, fryse, fringe” may be a later iteration, also derived from the root ᴹ√TAS (PE22/50 note #187).
Neo-Quenya: I would retain ᴺQ. tastë “fringe” for purpose of Neo-Quenya, but based on the Neo-Root ᴺ√TATH to avoid conflict with the later root √TAS “indicate”. I would not use atsa “fringe” since it conflicts with the more common ᴹQ. atsa “claw”; see that entry for discussion.
