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. nornelasse(a) “having oak-leaves” in the Qenya Lexicon of the 1910s, a combination of ᴱQ. norne “oak-tree” and ᴱQ. lassea “with leaves” (QL/67).
Neo-Quenya: Since Q. norno was a later form of the Quenya word for “oak”, I would update this word to ᴺQ. nornolassëa for purposes of Neo-Quenya.
