A person or company that provides assurance or insurance, guaranteeing something will happen or be protected.
From Old French assurer (to assure), from Late Latin assecurare (to make secure), combining ad- (to) + securus (secure). The -er suffix indicates one who performs the action.
Insurance companies are essentially professional assurors—they make their money by being really good at calculating risk and convincing people that their worry is worth transferring to someone else.
