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.
An (onomatopoeic?) noun appearing as ᴱQ. qā “a duck” in Qenya Lexicon of the 1910s derived from the early root ᴱ√QAHA (QL/76). It was also mentioned in the Poetic and Mythological Words of Eldarissa (PME/76). Later iterations of this onomatopoeia may be seen in primitive ✶kawāk “crow” (WJ/395) and ✶kāwāk “frog” (VT47/36), producing Q. quáco and Q. quácë respectively.
Neo-Quenya: I’d adapt this word as ᴺQ. quá “duck” for purposes of Neo-Quenya.
