“Ours is a geography of cataclysm: Santa Anas wreak their psychic wrath; the odor of disaster seeps from the street like that sulfurous egg smell of the La Brea Tar Pits.” — John Lopez, The Hollywood Reporter, 6 Sept. 2025

In its early days, wreak was synonymous with avenge, a meaning exemplified when Shakespeare’s Titus Andronicus proclaims “We will solicit heaven, and move the gods / To send down Justice for to wreak our wrongs.” This sense is now archaic, but the association hasn't been lost: although wreak is today most often paired with havoc, it is also still sometimes paired with words like vengeance and destruction. We humbly suggest you avoid wreaking any of that, however, no matter how badly you may crave your just deserts.
