A wreck is something that's been destroyed. Your hair might be a wreck after a bad day at the barber. Your car might be a wreck after you hit a telephone pole.
Your house might be a wreck after a visit from 3-year-old twins. You might be an emotional wreck after a fight with your boyfriend. A sunken ship is a wreck, or a shipwreck. When you hit that telephone pole, you’ve had a wreck, and you can also call your mangled car a wreck. When you’re next heading out with the car keys, you mom might say, "Don't wreck the car!,” hoping you’ll bring it back in one piece.
