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. helilokte “(purple cluster) wisteria” in the Qenya Lexicon, a combination of ᴱQ. helin “pansy [= purple flow]” and ᴱQ. lokte “(flower) cluster” (QL/39).
Neo-Quenya: Since I retain ᴺQ. helin “pansy” for purposes of Neo-Quenya, I would adapt this word as ᴺQ. helillos “wisteria, (lit.) purple cluster” using the later word lós “mass of flowers” for its second element.
