When we say something is a wreck, we generally mean that it is in a state of disrepair or damage. There are a number of synonyms that can be used to describe something that is in a similar state. For example, you might say that something is a shambles, a disaster, a mess, a catastrophe, or even a trainwreck. Each of these words has a slightly different connotation, but they all suggest that something is not working as it should or is in need of repair. Other possible synonyms might include dilapidated, run-down, or decrepit, which suggest that something is old and falling apart.
