“You could have + past participle” is used to talk about past possibilities or missed chances. It means something was possible in the past, but it did not happen. We often use it when giving advice, expressing regret, or pointing out a better option. For example, if your friend missed a train, you can say, “You could have left earlier.” In daily life, we use it in conversations at home, work, or with friends to talk about what was possible before. This structure helps you sound more natural and fluent in English speaking.
