Sink or swim是什麼意思

"Sink or swim" is an English idiom that means to succeed or fail on one's own efforts or abilities without any help or support from others. It suggests that the outcome will be determined by the individual's own actions and capabilities, without any external assistance.

The phrase is often used to describe a situation where someone is left to their own devices to figure something out or to achieve a goal, and their success or failure will depend entirely on their own efforts and skills. It can also be used to encourage someone to try their best and to rely on their own abilities, even if they are not sure of the outcome.

For example, "After weeks of training, it was time for him to go on stage and sink or swim." This means that he had to perform on his own, without any further training or support, and his performance would determine whether he succeeded or failed.
