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. saiqa “hungry” in the Qenya Lexicon under the early root ᴱ√SAẎA (QL/82). In Early Noldorin Word-lists of the 1920s, the Qenya word for “hungry” was instead saisa, though its Early Noldorin equivalent ᴱQ. haib seems to indicate primitive ✱saikwā (PE13/146).
Neo-Quenya: For purposes of Neo-Quenya I would retain the adjective ᴺQ. saiqua “hungry” based on a Neo-Root ᴺ√SAYAK, but only as an archaic word so I could justify the retention of related words like ᴺS. saeb “hungry”. For normal speech I would assume Q. maita is the ordinary word for “hungry” (VT39/11).
