What’s the difference between rack and wrack? Let’s take a look at their definitions, how to use them in popular phrases, and a mnemonic device to help you remember which is which.
Rack as a verb means “to torture or cause great suffering.”
Example: Her anxiety racked her mind.
Have you ever heard of the medieval torture device called the rack? It was a wooden frame with a crank attached to it. When a person was placed on the rack, the torturer would crank the device, stretching the person’s limbs until they dislocated them. Sounds like fun times.
Anyway, that’s where we get this usage of rack. And when we use it, we signify torturing, especially stretching.
Wrack as a verb means “to wreck or ruin something.”
Example: They sat back as they watched pollution wrack their planet.
Wrack comes from a word meaning “to be shipwrecked.” Both of these words have pretty gloomy origins, don’t they?
Now let’s go over a couple common phrases using one of these words.
Rack your brain
When you rack your brain, you are thinking really hard, stretching your brain’s capabilities. This idea of stretching is why we use rack instead of wrack.
Example: I really racked my brain studying for my chemistry final.
Something that is nerve-racking tortures your nerves. This idea of torturing is why we use rack instead of wrack.
Example: I found studying for my chemistry final nerve-racking.
It’s true that rack and wrack have very similar uses. This is why some dictionaries, such as Merriam-Webster, are advocating for using the words interchangeably and treating them as spelling variants.
To remember the difference between rack and wrack think: wrack = wreck. They are only one letter off.
