A noun appearing as ᴱQ. tuista “spray, twig, sprout, shoot” in the Qenya Lexicon of the 1910s under the early root ᴱ√TUẎU (QL/96).
Neo-Quenya: Since √TUY “sprout, bud” survives Tolkien’s later writings, I would retain ᴺQ. tuista, but only for the senses “twig, shoot” referring to small offshoots from a tree or similar plant. For “sprout” I would use [ᴹQ.] tuima (Ety/TUY).
