saikelta-

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 verb appearing as ᴱQ. saitya- “to starve” in the Qenya Lexicon of the 1910s based on the early root ᴱ√SAẎA “hunger” which was mostly used in combination with -kǝ (QL/82). Its ancient form is probably ✱saikya- with ky > ty (PE12/22). Tolkien said this verb was transitive as in “to starve [someone]”, but could be used impersonally to mean “I starve”. Tolkien also gave a variant form saikelta-, apparently a combination of ᴱQ. saike “hunger” with the verb suffix ᴱQ. -lta.
Neo-Quenya: I retain this verb as ᴺQ. saitya- for purposes of Neo-Quenya. Its impersonal use would be saitya ni “[it] starves me” = “I starve”.
