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 verb appearing as ᴱQ. qama- “am ill; vomit” in the Qenya Lexicon of the 1910s under the early root ᴱ√QAMA (QL/76).
Neo-Quenya: I’d retain ᴺQ. quam- “to be ill, vomit” for purposes of Neo-Quenya, especially since ᴹ√KWAM continued to be associated with sickness in Tolkien’s later writings (Ety/KWAM).
