Some things just go together. Like peanut butter and jelly. Like Katie and Couric. Like arsenic and old lace. You get the picture.
But few things go together with such strength as “wreaking” and “havoc.” Seriously, have you ever seen one word without the other? Try to use just one of those words in a sentence. I’ve never known a havoc that had not been wreaked. Well, June Havoc maybe. Early in her career.
Ask yourself: what would wreak do without havoc? While you are asking, has anything other than havoc ever been wreaked? The Wild Wind, that’s close. But I cannot dredge up any other word combination with such a knee-jerk response.
