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.
An adjective appearing as ᴱQ. kalaina or kalainea “serene” in the Qenya Lexicon of the 1910s under the early root ᴱ√KALA “shine golden” (QL/44). Kalaina also appeared in the contemporaneous Gnomish Lexicon as equivalent to G. glaim “serene, clear, fair (espec. of weather)” (GL/39), so it may originally have referred to clear weather.
Neo-Quenya: Since √KAL still referred to “light” in Tolkien’s later writings, I would retain ᴺQ. calaina “serene” for purposes of Neo-Quenya.
