The phrase wreak havoc means to cause chaos or destruction or both. The phrases play havoc and raise havoc mean the same thing. Havoc is associated with seriously destructive and chaotic situations, such as natural disasters, as in The hurricane caused havoc throughout the region. But it can be used in a range of situations. An illness can wreakhavoc on your body. A virus can cause havoc in a computer network. The wind can wreak havoc on your hair. In most cases, havoc causes a situation that was (at least somewhat) orderly to become disorderly, especially when there is damage or destruction involved.

Etymology

Origin of havoc

First recorded in 1400–50; late Middle English havok, from Anglo-French (in phrase crier havok “to cry havoc,” i.e., “utter the command havoc! ” as signal for pillaging), Middle French havot in same sense, from Germanic

Explanation

Havoc is a noun that means devastation or total mayhem. Havoc is often wreaked by hurricanes, angry mobs, plundering Vikings, and wild parties that get out of control. If we trace havoc way back, we arrive at a crossroads. Some people believe that the word comes from the Old French havot, meaning “plundering, devastation,” while others argue that it was passed down to us from the Latin habere, meaning “to have, possess.” Either way you look at it, the meaning remains the same: widespread disorder or destruction.
