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 unglossed root in the Qenya Lexicon of the 1910s with derivatives ᴱQ. ohte “egg” and ᴱQ. oi “bird, hen”; Tolkien speculated it was in fact the same root as ᴱ√OHO “cry” (QL/69). G. och “egg” from the contemporaneous Gnomish Lexicon is clearly related (GL/62), and probably also G. uil “hen” and G. uitha- “lay eggs, nest” given than they appear adjacent to uith “eggs”, the plural of och (GL/74). There are no signs of this root in Tolkien’s later writing, but I think it is worth retaining in Neo-Eldarin as ᴺ√OKH.
