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.
An unglossed root in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. vasa- “rush”, ᴱQ. vaska “making a plash or rush”, and ᴱQ. vasse “wing” (QL/100); in Qenya the root was blended with ᴱ√GWASA (QL/103). The distinction of the roots can be seen in their Gnomish derivatives: G. basbos “splash” and G. bass “wing, pinion” (GL/22) vs. G. gwass “rush, rushing, noise of rushing, splash” (GL/44). There are no signs of either of these roots in Tolkien’s later writing.
