Hi, welcome to a new episode of The Art of Business English. This week we are going to take a look at past modal verbs. This is an extension of last week’s episode on modals. If you didn’t get a chance to see that one, then you can review it by clicking here.
So, let’s turn to past modal verbs. What are they? Well, they are important to make deductions and to show different levels of certainty about past events. Also, they are used to express criticism or unfulfilled wishes. Using these verbs correctly will help you to get moving in the right direction to speak English naturally.
The general form for using past modals is: modal + have + past participle
Now let’s start learning how to use them in business contexts!
We use “must have” + past participle when we feel sure about what happened.
“Our security system shows that he swiped in with his badge at 8:14 AM, so he must have been in the office yesterday.”

May have/might have
We can use “might have” or “may have” + past participle to speculate about the past.
“If I had known about the traffic problems, I might have taken a different route to reach the office on time.”
“New entrants may have less access to capital than existing companies.”
“Could have” means that something was possible in the past, but it did not happen.
“Do you think we could have avoided the economic crisis if we had taken greater precaution?”
Business English Expressions
This 14 module course helps English language learners build their knowledge of business vocabulary and expressions and their understanding of them in different business scenarios.
We cover vocabulary for negotiating , decision making, leadership and many more.
Can't have/couldn't have
We use “can't have” and “couldn't have” + past participle when we think it's not possible that something happened. “Can’t have” has a stronger meaning than “couldn’t have” i.e., almost impossible.
“They can’t have finished the project yet because they only started working on it this week.”
“Our new hire is exactly what we needed. We couldn’t have asked for a better employee.”
“Should have” means that something did not happen, but we wish it had happened. We use “should have” to talk about past mistakes.
“I’m not a fan of their logo. I think they should have changed it years ago.”
We can use “shouldn’t have” when commenting on past errors or to criticise past behaviour.
“They shouldn’t have hired the mayor’s nephew; he’s too young.”
So, that’s a quick overview of past modal verbs and how we use them in English. What I have discovered is that they are very similar in use to Spanish, and they can be translated quite easily too. I always encourage my students to start using them, as once you start feeling comfortable using them, your English and they way you can discuss events in the past becomes so much easier and much more descriptive.
As always, if you have further questions or if you would like some advice, please leave me a comment on the blog or send me a message on Speakpipe.
If you would like to learn more grammar like this, then why don’t you enrol in one of my general English courses. We cover this grammar and a lot more.
Take care until next week.
