The correlatives ᴹQ. olde, ol, or onal(de) appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of ᴹQ. on- “identical” and ᴹQ. -l(de) “ways”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. imallë “in the identical way” using im- “same” and the later suffix -llë.
