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).
A word appearing as qāmea “sick” in Qenya Lexicon of the 1910s, an adjective form of ᴱQ. qáme “sickness, nausea” (QL/76).
Neo-Quenya: Since ᴹQ. qáme “sickness” appears in Tolkien’s later writings (Ety/KWAM), I would retain ᴺQ. quámëa for purposes of Neo-Quenya, but given the meaning of its noun form I would assume its primary meaning is “✱nauseous”, as opposed to generally sick which would be [ᴺQ.] hlaiwa.
