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.

A verb in the Qenya Lexicon of the 1910s glossed “wither” under the early root ᴱ√NṚQṚ (QL/68).
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.
The term ᴱQ. hesta appeared in the Qenya Lexicon of the 1910s with the gloss “the nearest consanguinity” (QL/40), that is the closest relative sharing a common ancestor, usually a sibling but possibly cousins if one has no siblings. The form hesta is followed by (-le) in parenthesis, which usually indicates a stem form but in this case probably indicates a variant form hestale. This word is derived from the early root ᴱ√HESE.
Neo-Quenya: I would retain this word for purposes of Neo-Quenya as a derivative of the Neo-Root ᴺ√KHETH.
