The mitre (British English) (/ËmaÉªtÉr/; Greek: Î¼Î¯ÏÏÎ±, headband or turban) or miter (American English; see spelling differences), is a type of headgear now known as the traditional, ceremonial head-dress of bishops and certain abbots in traditional Christianity.
In its modern form in Western Christianity, the mitre is a tall folding cap, consisting of two similar parts (the front and back) rising to a peak and sewn together at the sides. Two short lappets always hang down from the back.
