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. ínen appeared in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of the relative pronoun ᴹQ. i and the instrumental suffix ᴹQ. -nen.
Neo-Quenya: For purposes of Neo-Quenya I would update this to ᴺQ. yanen “whereby, by which” (originally coined by Helge Fauskanger in PPQ (PPQ) from the early 2000s) using the relative pronoun ya more commonly used in declined forms in later writings, such as Q. yassë “where [relative]”.
