Did You Know?

Disaster shall fall upon you, which you will not be able to expiate. That ominous biblical prophecy (Isaiah 47:11, RSV) shows that expiate was once involved in confronting the forces of evil as well as in assuaging guilt. The word derives from expiare, Latin for to atone for, a root that in turn traces to the Latin term for "pious." Expiate originally referred to warding off evil by using sacred rites or to using sacred rites to cleanse or purify something. By the 17th century, Shakespeare (and others) were using it to mean "to put an end to": "But when in thee time's furrows I behold, / Then look I death my days should expiate" (Sonnet 22). Those senses have since become obsolete, and now only the "extinguish the guilt" and "make amends" senses remain in use.
