kallevoite
adjective. fair (weather or complexion)
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.
ᴱQ. kalleva “fair (weather or complexion)” appeared in the Qenya Lexicon along with a variant ᴱQ. kallevoite, both adjectival forms of ᴱQ. kalle “fair weather” under the early root ᴱ√KALA “shine golden” (QL/44).
Neo-Quenya: I think this word might be salvaged as ᴺQ. calleva, since the later root √KAL was still associated with light, and this description of fair weather seems to boil down to “lightness”, as in the absence of obscuring clouds, and similarly for “fair complexion”.
