A word in the Qenya Lexicon of the 1910s glossed “device (method, trick), machine, engine”, based on ᴱ√ENE + ᴱ✶-yǝ whose derivatives had to do with devising and invention (QL/35). The parenthetical comment “device (method, trick)” seems to be for distinguishing its meaning from ᴱQ. enyarin “device, escutcheon, blazon” in the same entry.
Neo-Quenya: For purposes of Neo-Quenya I would update this word to ᴺQ. indya “device, machine, engine” as an elaboration of √IN(ID) “mind, thought”.
