Frequently Asked Questions

Do you rack or wrack your brain?

Wrack and rack are etymologically distinct, meaning they come from different words. Many usage guides will advise that you should use wrack for meanings such as "to utterly ruin," and rack for "to cause to suffer torture, pain, anguish, or ruin." If you follow this advice, the proper choice for what you do to your brain when thinking very hard is rack. However, wrack has long been used as a variant of rack, and numerous fine writers have avowedly wracked their brains or found something nerve-wracking.

Is it racked or wracked with pain?

Some guides feel that "racked with pain" is the preferable choice, although wrack is in many cases an acceptable variant. The verbs are often conflated despite their very different origins (the former from Middle Dutch rekken, meaning "to stretch," and the latter from the Middle English word for shipwreck, wrak).

"Do you rack up or wrack up debts?"

While there are a number of settings in which wrack is considered an acceptable variant of rack, the accumulation of debts is not one of them. In this context rack up typically means "to achieve, score; to accumulate."
