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. ausie “wealth” in the Qenya Lexicon of the 1910s under the early root ᴱ√AW̯A having to do with riches and property (QL/33).
Neo-Quenya: The root √AW “possess, own, keep” resurfaced in Late Notes on Verb Structure (LVS) from 1969, along with a derivative aura “possession, thing owned”. As such I would adapted this Early Qenya word as ᴺQ. aurië “wealth” as an abundance of possessions, an abstract noun based on aura.
