The term GOWN WORN BY THE CLERGY is a VESTMENT, which is an 8-letter word. A VESTMENT is a type of clothing worn by members of the clergy during religious ceremonies. It is typically made of fine fabrics such as silk or brocade and is often decorated with embroidery or other embellishments. Vestments are usually worn over a cassock, a long robe-like garment. The color of the VESTMENT is usually determined by the liturgical season or feast day.
