Some compound words (like bus rapid transit, dog whistle, or identity theft) don’t appear on the drop-down list when you enter them into the search window. If a compound term doesn’t appear in the drop-down list, try entering the term into the search window and then hit the search button (instead of the “enter” key). Alternatively, begin searches for compound terms with a quotation mark.

[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.]

Synonyms: destroy, raze, demolish, ruin, wreck
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).
The prosecutor demolished the opposition's argument. Ruin usually implies irretrievable harm but not necessarily total destruction: "You will ruin no more lives as you ruined mine" (Arthur Conan Doyle).
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).
