wreck (r
k)
n.1. The act of wrecking or the state of being wrecked; destruction.
2. Accidental destruction of a ship; a shipwreck.
3. a. The stranded hulk of a severely damaged ship.
b. Fragments of a ship or its cargo cast ashore by the sea after a shipwreck; wreckage.
4. The remains of something that has been wrecked or ruined.
5. Something shattered or dilapidated.
6. A person who is physically or mentally broken down or worn out.
From the definition....anything shattered or dilapidated can be a wreck. However, specifically concerning the sinking of ships, the word
accidentally is used (which rules out any deliberately sunken ships; such as war victims or artificial reefs). And yet... wreck can describe any hulk or fragment from a
shipwreck.
