qáme

noun. sickness, sickness, [ᴱQ.] nausea

A noun in The Etymologies of the 1930s glossed “sickness” under the root ᴹ√KWAM (Ety/KWAM). ᴱQ. qáme also appeared in the Qenya Lexicon of the 1910s with the glosses “sickness, nausea” under the early root ᴱ√QAMA (QL/76).

Neo-Quenya: For purposes of Neo-Quenya, I would assume this noun applies mainly to stomach illnesses and nausea, as opposed to general sickness which would be [ᴺQ.] hlívë.
