Khuzestan
Borrowing from Persian خوزستان (Xuzestân), from خوز (Xuz), name of the indigenous people of the region, and the suffix ـستان (-estân, “-stan”), or borrowed wholly from Middle Persian hwcstʾn' / 𐭧𐭥𐭰𐭮𐭲𐭭 (Hūzestān, literally “land of Hūz”), itself from hwc (Hūz) + -stʾn' (-estān, “-stan”). The first component is from Old Persian 𐎢𐎺𐎩 (hŪvja-, “Elam, Elamite”), or from the name of Susa. Compare Ancient Greek Οὔξιοι (Oúxioi), Classical Syriac ܒܝܬ ܗܘܙܝܐ (Bēṯ Hūzāyē), Old Armenian խուժ (xuž, “wild, savage”), Armenian խուժան (xužan, “mob”). The city name Ahvaz is also related.
