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.
A noun appearing as ᴱQ. saike (saiki-) “hunger” in the Qenya Lexicon under the early root ᴱ√SAẎA (QL/82). In Early Noldorin Word-lists of the 1920s, the Qenya word for “hunger” was instead saiste (PE13/147).
Neo-Quenya: For purposes of Neo-Quenya I would retain the noun ᴺQ. saicë “hunger” based on a Neo-Root ᴺ√SAYAK, but only as an archaic word so I could justify the retention of various famine-related words like ᴺQ. saicelë. For normal speech I would assume ᴺQ. maitië is the ordinary word for “hunger”, a noun form of the adjective Q. maita “hungry” from around 1960.
