A word in Quenya Notes from 1957 (QN) derived from the root √KEWE/KWĒ “live of vegetables” (PE17/159), so perhaps an adjective meaning “✱alive (of vegetables)”.
Conceptual Development: The word ᴱQ. lausiva “living (of plants)” appeared in the Qenya Lexicon of the 1910s as an adjective form of ᴱQ. laute “living thing, esp. vegetable” (QL/52).
