The Holy Rosary, also known as the Dominican Rosary, or simply the Rosary, refers to a set of prayers used in the Catholic Church and to the string of knots or beads used to count the component prayers. When referring to the prayer, the word is usually capitalized (“the Rosary”, as is customary for other names of prayers, such as “the Lord’s Prayer”, and “the Hail Mary”); when referring to the beads, it is written with a lower-case initial letter (“a rosary bead”).
