In this English lesson I'll give an introduction, with plenty of examples, on how to use the past modals: must have, should have, would have, and could have. This is a difficult topic for many English learners. I will do my best to make it clear how to use these verbs in some situations.
This is by no means meant to be an extensive lesson. In fact, I decided to leave some verbs off the list, and to simply help you learn some of the common ways we use these as native English speakers.
I hope this English lesson helps you, and if you want, please let me know in the comments if you want a more advanced class on this in the future.
Thanks for watching this English lesson about past modal verbs! Have a great day!
