The modals of speculation “must have,” “may have,” “might have,” “could have,” and “couldn’t have” are used to express different degrees of possibility or probability about something that happened in the past.
Here are some explanations of each modal and how they are used:
- “Must have” is used when you are certain that something happened in the past. For example: “He must have left early because his car is not here.” This means that you are confident that he left early, based on the evidence of his missing car.
- “May have” is used when you are not certain about something that happened in the past, but you think it is possible. For example: “She may have forgotten her phone at home.” This means that you think it is possible that she forgot her phone, but you are not sure.
- “Might have” is similar to “may have” and is also used when you are not certain about something that happened in the past, but you think it is possible. For example: “He might have missed his flight.” This means that you think it is possible that he missed his flight, but you are not sure.
- “Could have” is used when you are talking about a possibility in the past. For example: “He could have studied harder for the exam.” This means that he had the possibility to study harder for the exam, but you don’t know whether he did or not.
- “Couldn’t have” is used to express a strong belief that something did not happen in the past. For example: “He couldn’t have stolen the money because he was with me the whole time.” This means that you are confident that he did not steal the money, based on the evidence that he was with you the whole time.
