About This Root

From Old French seur (safe, secure), from Latin sēcūrus (free from care). The "secure" sense runs through the family: sure (certain), assure (make secure), ensure (make certain), insure (protect against loss), and reassure (restore confidence). Insurance preserves the original protective meaning most directly.
