Cách sử dụng
The expression "leave somebody/something to the mercy/mercies of somebody/something" is used when someone or something is not given any protection or help and is left in the hands of someone else or something else. This means that the person or thing will have to suffer and rely on the mercy of the other person or thing. For example, if you leave your pet dog outside in a harsh snowstorm, you are leaving it to the mercy of the cold weather. It can also be used in a more serious context, such as leaving someone to the mercy of a dangerous criminal or leaving a country to the mercy of a foreign enemy.
