[Middle English destroien, from Old French destruire, from Vulgar Latin *dēstrūgere, back-formation from Latin dēstrūctus, past participle of dēstruere, to destroy : dē-, de- + struere, to pile up; see ster-2 in the Appendix of Indo-European roots.]

These verbs mean to cause the complete ruin or wreckage of something or someone. Destroy, raze, and demolish can all imply reduction to ruins or even complete obliteration: "I saw the best minds of my generation destroyed by madness" (Allen Ginsberg). "raze what was left of the city from the surface of the earth" (John Lothrop Motley).

To wreck is to ruin in or as if in a violent collision: "The Boers had just wrecked a British military train" (Arnold Bennett).
When wreck is used in referring to the ruination of a person or of his or her hopes or reputation, it implies irreparable shattering: "Coleridge, poet and philosopher wrecked in a mist of opium" (Matthew Arnold).
