Tense Past Perfect – past perfect, or „the past of the past”

The tense Past Perfect is the tense we use when we want to organize events in the past. When we talk about something that happened, but suddenly we want to mention something that took place even earlier, this tense comes to the rescue.

Part 1: For beginners (Fundamentals)

The main rule is: if you are telling a story about the past and have two events, one of which happened before the other, for that older event („action 1”) you use the tense Past Perfect.

1. How do we build sentences?

The construction is very simple for all persons, as the operator always looks the same:

• Subject (e.g. I, he, they).
• Auxiliary verb had (often shortened to ’d, e.g. I’d, she’d). In negatives, we use hadn’t.
• Main verb in the III form (Past Participle) – that is, we add -ed to regular verbs (e.g. worked) or take the form from the 3rd column of the irregular verbs table (e.g. gone, seen).

Examples of usage:

• When I arrived at the station, the train had already left. (When I arrived at the station, the train had already left – first the train left, then I arrived).
• I didn’t have any money because I had lost my wallet. (I didn’t have money because I had lost my wallet earlier).
• Had you eaten breakfast before you left? (Did you eat breakfast before you left?).

2. Words that should raise a „red flag”

This tense loves expressions indicating the order of events:

• before (before)
• after (after)
• by the time (by the time)
• already (already) / just (just)

Part 2: For advanced learners (Nuances and contexts)

The tense Past Perfect is also essential for handling more advanced grammatical constructions in English.

1. Reported Speech

When we report someone’s words, we „backtrack” the tense by one (this is called sequence of tenses). If someone originally used the tense Past Simple or Present Perfect, in reported speech they change to Past Perfect.

• Original: „I lost my keys,” John said. (I lost my keys, John said).
• Reported speech: John said that he had lost his keys. (John said that he had lost his keys).

2. Third Conditional

This is used for so-called „what ifs about the past” – describing situations that did not happen and cannot be changed anymore. In the conditional part of the sentence after if, we use Past Perfect.

• If I had studied harder, I would have passed the exam. (If I had studied harder, I would have passed the exam – but I didn’t study and I didn’t pass).
• If she hadn’t missed the bus, she wouldn’t have been late. (If she hadn’t missed the bus, she wouldn’t have been late).

3. Expressing regret with the word „wish”

If we regret something that happened in the past, after the word wish we use the past perfect tense.

• I wish I had bought that house. (I wish I had bought that house. / I would like that I had bought that house).

4. Let’s catch the difference: change of meaning depending on the tense

Compare these two sentences. The choice of tense completely changes the picture of the situation:
