The merchants are considered as more immediately under the protection of the Mohassil, and therefore not so subject to the Avanias made by the Bashaw.
Where it comes from
Borrowed from Italian avania, from Byzantine Greek ἀβανία (abanía, cfr. modern Greek αβανιά (avaniá) “defamation, slander”), possibly from Arabic خَوَّان (ḵawwān, “unreliable, treacherous”).
