What is Rip: Definition and 201 Discussions

Rest in peace (RIP) is a phrase from the Latin requiescat in pace (Classical Latin: [rekʷiˈeːskat in ˈpaːke], Ecclesiastical Latin: [rekwiˈeskat in ˈpatʃe]), is sometimes used in traditional Christian services and prayers, such as in the Catholic, Lutheran, Anglican and Methodist denominations, to wish the soul of a decedent eternal rest and peace.
It became ubiquitous on headstones in the 18th century, and is widely used today when mentioning someone's death, regardless of religion.
