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.
The word ᴱQ. nyēni “she-goat” appeared in the Qenya Lexicon of the 1910s as a feminized form of ᴱQ. nyé “bleat” (QL/68). It also appeared in the Poetic and Mythological Words of Eldarissa (PME/68).
Neo-Quenya: I’d retain ᴺQ. nyéni for “(she) goat” for purposes of Neo-Quenya; see ᴺQ. nyé “bleat” for the rationale, and ᴺQ. naico “goat” for possible alternatives.
