The correlative ᴹQ. onima “of identical kind” appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/107), a combination of ᴹQ. on- “identical” and ᴹQ. -ima “kind”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. imaitë “of identical kind” using im- “same” and the later suffix -itë, as in taitë “of that sort”.
