Past Perfect Tense

The past perfect tense is used to describe an action that was completed before another past action or point in time. It helps to show the sequence of events in the past. To form the past perfect tense, we use the auxiliary verb "had" followed by the past participle of the main verb. The past participle form of regular verbs is formed by adding "-ed" to the base form of the verb, while irregular verbs have different forms.

Here's an example:

"I had already eaten breakfast before I left for work."

In this sentence, "had already eaten" is the past perfect tense. It shows that the action of eating breakfast was completed before the past action of leaving for work.
