Altered from Jaggernaut, a title of Krishna (an incarnation of Vishnu), from Hindi Jagannath, literally “lord of the world,” from Sanskrit jagat “world” (literally “moving,” present participle of *jagati “he goes,” from PIE *gwa- “to go, come” (see come (v.)) + natha-s “lord, master,” from nathate “he helps, protects,” from PIE *na- “to help.” The first European description of the festival is by Friar Odoric (c.1321). Figurative sense of “anything that demands blind devotion or merciless sacrifice” is from 1854.
