There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
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.
