使用する際の注意点

In senses “torture” and “suffer pain”, frequently confused with wrack (“destroy”) (more rarely, wrack (“wreckage”)), both as stand-alone verb and in compounds.^[1] In most uses, rack is correct, and wrack is incorrect.^[2] Etymologically, nerve-racking (“stressful”), pain-racked, and rack one's brain, rack one's brains (“think hard”) are correct, while rack and ruin and storm-racked are incorrect variants of wrack and ruin (“complete destruction”) and storm-wracked (“wrecked by a storm”).

Usage guidance differs: either prefer the etymologically correct term, prefer rack to (archaic) wrack, or use either. The etymologically correct forms are preferred by some style guides,^[3] but the unetymological forms are well-established and in wide use, and other style guides simply consider them variant spellings.^[4] Other style guides categorically ban wrack as archaic, suggesting modern synonyms like wreck, ruin, or destroy.^[5] In some cases style guides are confused by the etymology, or feature unhistorical forms such as nerve-wracking.^[6]

This confusion dates to Early Modern English in the 16th century (as in rack かつ ruin), and is presumably due to the influence of ⟨wr⟩ in words such as wreak, wreck, wrench, etc., which connote discomfort and torment.^[7] Formally termed the graphaesthesia of the graphaestheme ⟨wr⟩, since identical sound /r/ to ⟨r⟩; compare with phonaesthesia.^[8] Compare rapt/wrapt, and also ⟨gh⟩ as in ghost and ghastly.
