The term ROSARY COMPONENT can be solved by the four letter word BEAD. A rosary is a set of beads used in prayer, usually associated with the Catholic faith. The beads are used to keep track of the prayers being said and are often made of wood, glass, or metal. Each BEAD represents a specific prayer or part of a prayer. The component of the rosary that is referred to as a BEAD is the individual piece that is used to count the prayers.
