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 Qenya name for Moon in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa from the 1910s (QL/83; PME/83), a combination of silma “ray of moonlight” an rinko “orb”. It also appeared in the reduced form Silmarint, where after the loss of the final vowel the [[eq|final [k] became [t]]]. Another variant Silmarindo also appeared, of less clear origin.
