The English word is derived from the Latin , as compline is the completion of the waking day. The word was first used in this sense about the beginning of the 6th century in the Rule of Saint Benedict (Regula Benedicti; hereafter, RB), in Chapters 16, 17, 18, and 42, and he uses the verb compleo to signify compline: "Omnes ergo in unum positi compleant" ("All having assembled in one place, let them say compline"); "et exeuntes a completorio" ("and, after going out from compline")… (RB, Chap. 42).
