A Chaplet is a form of Christian prayer which uses prayer beads.
What is a Chaplet? Like the rosary, a chaplet is a sacramental. It consists of prayer beads, and on each bead one says certain designated prayers. There are many different types of chaplets. Often they honor Our Lord or the Blessed Mother under a particular title, such as the Chaplet of the Sacred Heart or the Seven Dolors Chaplet, and are special ways of practicing these Catholic devotions. Some chaplets honor and ask the intercession of particular Saints, such as the Chaplet of St. Anthony, St. Philomena, etc.. Chaplets are also known to be powerful aids in obtaining certain virtues, such as the Immaculate Conception Chaplet which is prayed to obtain and preserve purity, or the Chaplet of St. Patrick which is a special prayer for an increase in Faith.
