A word appearing as ᴱQ. enyarin “device, escutcheon [an emblem or shield bearing a coat of arms]” in the Qenya Lexicon of the 1910s, an elaboration of ᴱQ. enya “device, machine, engine” under the early root ᴱ√ENE (QL/35). The word enyarin was glossed “blazon” in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/35). As such it seems this word applied to shields, emblems and flags bearing a coat of arms or other symbol representing a person or organization.
Neo-Quenya: Since I adapt ᴱQ. enya “device, machine” as Neo-Quenya ᴺQ. indya, I would likewise adapt this word as ᴺQ. indyarin “device, escutcheon, blazon”.
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”.
