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 correlative ᴹQ. manima “of what kind, what kind of” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/107), a combination of interrogative ᴹQ. ma and ᴹQ. -ima “way, manner”. It also appeared in the Quenya Verbal System (QVS) from this same period (PE22/124).
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. manaitë “of what kind, of what sort, what kind of” using the later suffix Q. -itë. Compare Q. taitë “of that sort”.
