A word appearing as G. tast “border, fringe” (GL/69), clearly based on the early root ᴱ√TASA which had a derivative ᴱQ. taste “fringe” in the contemporaneous Qenya Lexicon (QL/89).
Neo-Sindarin: Since I retain ᴺQ. tastë “fringe” based on the Neo-Root ᴺ√TATH, I would retain ᴺS. tast “border, fringe” for purposes of Neo-Sindarin as well.
