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√ENE¹ (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”.
