Understanding the Usage of 'Could Have Had', 'Should Have Had', and 'Would Have Had' in English

When discussing modal verbs in English, some forms like 'could', 'should', and 'would' can sometimes be confusing, especially when they are combined with the auxiliary verb 'have'. This article will clarify the usage of 'could have had', 'should have had', and 'would have had', and explain the difference between these and the past perfect tense. Let's dive into the nuances of these modal verbs and their perfective aspects.

Introduction to the Modal Verbs 'Could', 'Should', and 'Would'

The modal verbs 'could', 'should', and 'would' are part of the family of auxiliary verbs, which are used to express certain grammatical functions, such as possibility, obligation, and future, among others. However, they do not have a specific tense on their own. For instance:

The present tense forms are: 'can', 'shall', and 'will' The past forms (which they used to have) were: 'could', 'should', and 'would' These past forms, now considered historic or modal past forms, operate more like tenses without a specific tense meaning in themselves

Perfect Modals and Their Usage

When these modal verbs are used with 'have', they take on a different meaning, becoming what is called 'perfect modals'. Perfect modals can express past time, but only in a negative sense or used in conditional sentences. Here are some examples to illustrate:

Counterfactual Conditions

'If I had known you were coming, I could/would have made dinner.'

Here, 'could have' and 'would have' are used to express a hypothetical situation that did not happen, which often involves an apology or regret for not doing something.

Negative Utterances

'I should have cleaned the house yesterday but I didn’t.'

In this sentence, 'should have' indicates a failure to do something that was expected or should have been done.

The Past Perfect Tense: A Different Concept

It is crucial to differentiate the past perfect tense from the use of perfect modals with 'could', 'should', and 'would'. The past perfect tense is used to describe an action that took place in the past before another past action. It is formed by 'had past participle'. Here is an example:

Timing of Actions in Past Events

'We had just arrived home when the storm began.'

In this sentence, 'had just arrived' shows that one event happened before another. However, it is worth noting that in everyday usage, the past perfect is not as frequently employed as the simple past tense.

Grammar and Linguistic Insights

Let's consider the grammar of these modal verbs in more detail. Some insights into the usage of 'could', 'should', and 'would' with 'have' may reveal that while 'could have had' might be interpreted as a form of past perfect, it is more accurately described as a perfect modal. The phrase 'could have had' expresses a hypothetical past situation that did not occur. Conversely, the past perfect tense would be used to describe a sequence of past events, as seen in the example 'We had just arrived home when the storm began.' Here, 'had arrived' shows a sequence of events.

Another grammarian-user notes that while the phrase 'would have had' can be seen as expressing a past future perfect, it is a bit humorous to see it defined this way. Grammatically, the past future perfect would be a construction like 'would have had done', but this structure is less common in everyday speech.

Conclusion

In summary, while 'could have had', 'should have had', and 'would have had' are often seen with the auxiliary verb 'have', they are not the same as the past perfect tense. Perfect modals are used to express hypothetical or past situations, and they often do not convey the same sequence of past events as the past perfect tense. Understanding the difference is essential for mastering the nuances of English grammar.
