disc▪ Youssef2003 thinks the word is from Copt ḥnau < Eg ḥnw ‘metal cooking pot shaped a little like a wok’. – Cf. Crum1939: Copt ḥn(a)au ‘vessel, pot, receptacle’; ErmanGrapow1921: Eg ḥnw ‘vessel, receptable’ > Copt ḥnaau, Eg ḥnw.t ‘bowl, cup’). – Phonetically perhaps not impossible, though not really probable. But the fact that the item seems to be peculiar to EgAr makes a Copt origin quite likely.
