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.

Title of the nine great male Valar appearing in The Etymologies from the 1930s as a combination of Vala and tar- “king” (Ety/BAL, TĀ). Its (ᴹQ) genitive and plural forms Valatáren and Valatári indictate that its stem form is Valatár-. In Lord of the Rings drafts from the 1940s, Tolkien consider this as a name for Aragorn’s father (TI/363).
