The term ROSARY UNIT can be broken down into two parts: BEAD, which is a 4 letter word, and UNIT. A rosary UNIT is a single BEAD in a string of beads that make up a rosary. Rosaries are used in prayer by members of the Catholic faith, and each BEAD represents a prayer or meditation. The rosary is made up of five sets of ten beads, with one larger BEAD between each set. The larger BEAD is known as the 'Our Father' BEAD, and is used to mark the beginning and end of each set of ten.
