Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
The correlative ᴹQ. qalde or qaqil(de) appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of ᴹQ. qa(qe)- “all” and ᴹQ. -l(de) “ways”.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. illë “in all ways” using il- “all” and the later suffix -llë.
