“Should have,” “could have,” and “would have” are all modal verbs that are used to talk about past events that did not happen, or hypothetical scenarios that didn’t occur in the past.
“Should have” is often used to express regret or to suggest that something would have been a good idea. For example, “I should have studied more for the exam” implies a regretful acknowledgment that not studying enough may have hurt one’s performance on the exam.
“Could have” is used to indicate that something was possible or feasible, but didn’t actually happen. For instance, “I could have taken that job offer” means that one had the option to take the job but didn’t.
“Would have” can indicate a hypothetical scenario that didn’t occur in the past, or a conditional scenario where an action in the past would have led to a different result. For example, “If I had known about the traffic, I would have left earlier” indicates that the person didn’t know about the traffic beforehand but would have left earlier if he or she had known.
Overall, these modal verbs are used to talk about what could have happened in the past, but didn’t, or to express regret about past actions or decisions.
