The past tense is fairly easy to comprehend. When we talk to our friends we use past, present, and future tenses with ease, but as writers we use other tenses to enhance our work and help explain the sequence of events to our readers. One of these is the past perfect tense, which is, in essence, a little more past than past. When used correctly, this tense tells the reader that we're going back in time, even beyond the usual past tense that is employed in most fiction. Technically speaking, it is used to refer to a noncontinuous action in the past that was already completed by the time another action in the past took place.
The past perfect can be very useful in fiction writing because you can go back to a previous event without confusing your reader.
She had worried about her sister's drug problem when their mother died and had taken steps to find a suitable rehab program. But her sister continued to push her away over the years, and eventually, Joann decided to step back from the problem and stay available should her sister need her. She knew how stubborn and independent Julie could be.
It can also be annoying if overdone. Once you've established that you're going back in time, you can revert back to the simple past tense. In the above example, we reverted back to the past tense after "rehab program." The flashback had already been established, and there was no need to continue with the past perfect.
The past tense becomes the past perfect with the addition of the verb "to have."
Past: I wrote that poem.
Past perfect: I had written that poem.
The past perfect tense implies that I wrote that poem before something else happened, as in "I had written that poem before experiencing a broken heart." Another example:
Past: I wanted to learn more about Italy, so I called my friend Stephanie, who lived in Floronce. Stephanie was probably still in Florence at the time of the call.
Past perfect: I wanted to learn more about Italy, so I called my friend Stephanie, who had lived in Florence for several years. Stephanie no longer lives in Florence.
