Past Perfect Tense - Definition, Formula, Structure, How to Use It, Examples

The past perfect tense is a verb form which is used to refer to a past action that occurred before another past action. It helps clarify the order of events in a sentence. This tense is formed using “had” along with the past participle of the main verb (e.g., “She had finished her homework before dinner.”). Using the past perfect tense can provide context and background information about past situations.

Definition of the Past Perfect Tense

According to the Oxford Advanced Learner's Dictionary, "the past perfect tense is a verb form that describes an action that was completed before a specific point in the past."

According to the Cambridge Dictionary, "the past perfect tense is a verb form that indicates an action that was completed before another action happened. It is formed by combining the word "had" with a past participle." 

The past perfect tense is formed using the auxiliary verb "had" followed by the past participle of the main verb. The formula can be summarized as follows:

Past Perfect Tense Structure: Subject + had + past participle + the rest of the sentence

Examples:

• I had finished my homework.
• They had left before I arrived.

The structure of the past perfect tense and their formula can be easily understood by knowing how to use it in four different types of sentences: positive, negative, interrogative, and negative interrogative. The below-mentioned table provides a clear overview of how to form different types of sentences using the past perfect tense, along with relevant examples for each form.

1. Time Reference: The past perfect tense always refers to a time in the past. It is used when discussing two actions that happened at different times in the past.

Example:

By the time she arrived at the party, everyone had already left.

(In this sentence, "had left" indicates that the action of leaving happened before she arrived.)

2. Contextual Clarity: Using the past perfect helps clarify which action occurred first, making your sentences clearer and more informative.

Example:

He had finished his homework before he went out to play.

(Here, "had finished" shows that finishing the homework was completed before going out to play, providing a clear sequence of events.)

Not Always Required: While it is useful for indicating sequences, it is not always necessary to use the past perfect if the meaning is clear without it. However, using it can enhance your writing and speaking by providing additional context.

Example:

She ate breakfast and then left for work.

(This sentence is clear without using the past perfect.)

When learning the past perfect tense, students often encounter several common mistakes that can lead to confusion and incorrect usage. Here are some of the most common errors, along with explanations and examples to help you avoid them.

Using Past Perfect Instead of Simple Past: One common mistake is using the past perfect tense when it is not necessary. The past perfect is used to indicate that one action was completed before another action in the past. However, if you are simply stating an action that happened at a specific time, the simple past tense should be used instead.

• Incorrect: I had been to New York recently.
• Correct: I went to New York recently.

Failing to Indicate a Sequence of Events: The past perfect tense should be used to clarify the order of events when discussing two actions in the past. If you do not indicate which action occurred first, it can lead to confusion.

• Incorrect: He said that he was suffering from fever for three days.
• Correct: He said that he had been suffering from fever for three days.

Overusing the Past Perfect Tense: Some have the tendency to overuse the past perfect tense, applying it unnecessarily in situations where it does not add clarity. It should only be used when necessary for understanding the sequence of events.

• Incorrect: She had drunk her coffee and then had run out of her house.
• Correct: She drank her coffee and then ran out of her house.

Using Incorrect Forms of Verbs: Students often struggle with irregular verbs and their past participles, which can lead to mistakes when forming the past perfect tense. It’s important to remember the correct past participle forms.

• Incorrect: We didn’t seen the film before yesterday.
• Correct: We hadn’t seen the film before yesterday.

Misusing "Had Had":
The phrase "had had" can be confusing for learners because it involves using "to have" in both its auxiliary and main verb forms. Remember to use it correctly when necessary.

• Incorrect: She had her makeup done before we went out.
• Correct: She had had her makeup done before we went out.
