A neologism for “appliance” created by Petri Tikka in Parma Penyanë Quettaron (PPQ) from the early 2000s, an instrumental formation based on ᴹ√YUK “employ, use” + ancient suffix ✶-mā, where km > gm > ñm > ñgw. Sometime around 1960, Tolkien updated this phonetic development so that km > kw instead (PE19/85), and in that later paradigm this word would be ᴺQ. yuqua “appliance”. I prefer the earlier paradigm, however, so I would keep Petri Tikka’s word yungwa for purposes of Neo-Quenya.
