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 word appearing as ᴱQ. ulumpe or ulun (ulunt-) “camel” in the Qenya Lexicon of the 1910s (QL/97). The contemporaneous Poetic and Mythological Words of Eldarissa had ulump(e)- “camel” (PME/97). Under the early root ᴱ√KUPU “hump” Tolkien had a different form ᴱQ. kuptulo for “camel”, but this was deleted (QL/49).
Neo-Quenya: I think this word may be preserved as ᴺQ. ulumpë “camel” based on a Neo-Root ᴺ√LUP “hump”.
