The term 'Bishop Toppers' refers to a type of headgear worn by bishops in the Catholic Church. The headgear is also known as a miter, which is a six-letter word that can be found in crosswords. Bishop Toppers are typically made of stiffened fabric and are decorated with embroidery or jewels. They are usually white and have two peaks that come to a point at the top. The miter is an important part of the bishop's vestments and is a symbol of his spiritual authority.
