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 noun for {“ember, smouldering brand” >>} “ember, smouldering wood” based on the root ᴹ√YUL “smoulder” in The Etymologies of the 1930s (Ety/YUL; EtyAC/YUL). The later meaning of the root √YUL was “drink” (PE17/63).
Neo-Quenya: For purposes of Neo-Eldarin, I would adapt the root ᴹ√YUL “smoulder” as the Neo-Root ᴺ√YOL/YUL with vowel variations similar to √SOK/SUK and as such would salvage this word for the purposes of Neo-Quenya; see the entry on ᴺ√YOL/YUL for further discussion.
