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 verb appearing as tinga- “twang” in The Etymologies of the 1930s glossed derived from the onomatopoeic root ᴹ√TING or ᴹ√TANG (Ety/TING). The Quenya Verbal System (QVS) of 1948 instead had tanga- with past forms tange or tangane “twanged”, derived from ᴹ√TAÑ.
Neo-Quenya: In a 2025-01-30 post to the Vinyë Lambengolmor Discord Server (VLDS), Luinyelle suggested this verb might also mean “✱ping” in the modern internet sense, as in tinganel nin “you pinged me”.
