The prefix for singular “some” in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/99), used in formations like ᴹQ. umallume “some time” and ᴹQ. umas(se) “✱somewhere”. It is probably related to the interrogative root √MA, which is also the based for (later) ma “something”. See the entry on correlatives for further discussion.

The correlative ᴹQ. qáqima or qáqanima “of any kind, of all sorts” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/107), a combination of ᴹQ. qa(qe)- “all” and ᴹQ. -ima “-kind, -sort”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. ilítë “of all kinds, of all sorts” using il- “every” and the later suffix -itë, as in taitë “of that sort”.
