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 noun appearing as {laume >>} ᴱQ. lauste “life, mode of life” in the Qenya Lexicon of the 1910s under the early root ᴱ√LAWA “✱life (of plants)” (QL/52). Tolkien also gave laule = laume, so presumably this was also equivalent to lauste. The word laume “life” also appeared (undeleted) in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/52).
Neo-Quenya: Since √LAW had a similar meaning in Tolkien’s later writings, I’d retain ᴺQ. laulë “mode of life” for purposes of Neo-Quenya, along with other words derived from it. In the “Neologism of the Day” (NotD) series on the Vinyë Lambengolmor Discord Server (VLDS) posted at 2023-06-18, Valerie suggested this word might mean “✱lifestyle” as well.
