The core modal verbs in English are: can, could, may, might, shall, should, will, would, must, and ought to. They are unique because they do not change form according to tense or subject and are followed by the base form of the main verb without a particle to.

For advanced learners

"Ought to have" and "should have" are part of modal verb constructions and are used to express past obligations, advice, or expectations that were not met or followed. Let's delve into their use and meaning.

1. "Ought to Have"

"Ought to have" is used to indicate that something was the correct or advisable action in the past, but it was not done. It carries a sense of regret or missed obligation. We use them in the present perfect mostly.

• You ought to have told me about the meeting.

• Meaning: It was the right thing to do, but you did not tell me.

2. "Should Have"

"Should have" is similar to "ought to have" and is used to express that a different action would have been better or more advisable in the past. It often implies a sense of regret or missed opportunity.

• You should have called me when you arrived.

• Meaning: Calling me was the advisable action, but you did not do it.

Using "Ought to Have" and "Should Have" in Sentences

Both "ought to have" and "should have" are followed by the past participle of the main verb.

Examples:

1. Obligation Not Met:

• She ought to have submitted her report last week. (It was expected, but she did not do it.)

• You should have finished your homework by now. (It was expected, but it is not finished.)

1. Advice Not Taken:

• We ought to have taken a different route to avoid the traffic. (Taking a different route was advisable, but we did not do it.)

• He should have listened to the weather forecast before leaving. (Listening to the forecast was advisable, but he did not do it.)

1. Expectations Not Fulfilled:

• They ought to have arrived by now. (It was expected, but they have not arrived.)

• I should have received the package yesterday. (It was expected, but I did not receive it.)
