The term 'liturgical headdress' refers to a type of headgear worn by members of the clergy during religious ceremonies. The most common form of liturgical headdress is the miter, which is a five-letter word. The miter is a tall, pointed hat that is often decorated with symbols and designs that represent the faith of the wearer. It is typically made of cloth or metal and is worn by bishops, cardinals, and other high-ranking members of the clergy. The miter is an important part of many religious ceremonies and is a symbol of the authority and power of the clergy.
