Create confusion and inflict destruction. Havoc, which comes from the medieval word for “plunder,” was once a specific command for invading troops to begin looting and killing in a conquered village. This is what Shakespeare meant by his oft-quoted “Cry ‘havoc’ and let slip the dogs of war” (Julius Caesar, 3.1). Although the word still means devastating damage, to wreak it has been transferred to less warlike activities, as in “That puppy will wreak havoc in the living room.” Henry Wadsworth Longfellow in the The Birds of Killingworth (1863) stated, “The crow . . . crushing the beetle in his coat of mail, and crying havoc on the slug and snail.”See also: havoc, wreak
