✔ In deep water
If you’re in deep water, you’re in some sort of trouble or in a difficult situation.
■ For example:
- The company’s in deep water now that the tax inspectors have decided to check over the accounts.
- Many families are in deep water because of the mortgage crisis, and some might even lose their homes.
■ Origin: Probably metaphorical, and related to the fact that deep water can be very dangerous, especially if someone can’t swim.
