Here is a context clues worksheet on the noun havoc, which means “wide and general destruction” “devastation,” and “great confusion and disorder.” The context clues in this worksheet point to both definitions, so students will very likely figure this out quickly.
Interestingly, while researching this post, I learned that havoc also has use as a transitive verb meaning “to lay waste” and “destroy.” Havoc is often used with active verbs like cause and of course the always dependable wreak–although please beware that contentious debate has broken over the past tense (wrought or wreaked?) of this verb.
