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.
Apparently an adverbial form of ᴱQ. lausta- “to roar, rush” in drafts of the Oilima Markirya from around 1930 (PE16/57, 60), in context perhaps meaning “✱noisily” as suggested by Gilson, Welden and Hostetter (PE16/59).
