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 name of Melko in the Qenya and Gnomish Lexicons from the 1910s (QL/106; GL/18), along with other early name lists (PE13/103; PE14/12). It was derived from the root ᴱ√DYELE having to do with the cold (QL/106). The variants Yeloimu and Yelusto also appeared (GL/38; PE13/103; PE15/24).
