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!
A word appearing as ᴱQ. helinwa “of pansies; of colour = a blue-violet” in the Qenya Lexicon of the 1910s, an adjective form of ᴱQ. helin “pansy” (QL/39).
Neo-Quenya: Since I retain ᴺQ. helin “pansy” for purposes of Neo-Quenya, I would retain ᴺQ. helinwa “of pansies; (of colour) a blue-violet” as well.
