Did You Know?

The classical Latin adjective spurius started out as a word meaning "illegitimate." In the days of ancient Rome, it was sometimes even used as a first name for illegitimate offspring (apparently with no dire effects). There was a certain Spurius Lucretius, for example, who was made temporary magistrate of Rome. In less tolerant times, 18th-century English writer Horace Walpole noted that Henry VII "came of the spurious stock of John of Gaunt." Today, we still use spurious to mean "illegitimate," but the more common meaning is "false" (a sense introduced to spurious in Late Latin). Originally our "false" sense emphasized improper origin, and it still often does ("a spurious signature"), but it can also simply mean "fake" or "not real."
