The past perfect simple

Build the past perfect

Use had + past participle. Had stays the same with I, you, he, she, it, we and they. The past participle is the verb form used after have in a perfect tense: packed, taken, written or been.

A regular verb has an -ed participle, such as packed. An irregular verb may have a different form: take, took, taken. Learn the participle, not just the past simple. See The present perfect: form and uses for more forms.

Hadn't means had not. You can shorten had to 'd: Zara'd taken it. We'd packed. Here 'd means had. In I'd like a seat it means would instead: the following verb pattern helps you read the contraction.

Put a question word before had: Where had Zara put it? Short answers keep had or hadn't: Had they paid? Yes, they had. No, they hadn't. Do not add did to this question pattern.

An earlier event from a later past viewpoint

First choose the past point you are looking back from. The past perfect places something before that point. The later point can be an event or a time such as noon yesterday.

• When the visitors arrived, the guide had opened the gate.

Opening happened first. The visitors arrived later, so the gate was already open at their arrival. You can reverse the clause order without changing that sequence.

• The guide had opened the gate when the visitors arrived.
• By noon yesterday, the team had checked every room.

By noon means no later than noon. The checks were complete by that past point; the sentence does not give the exact time of every check. 'Up to a past point' describes the time period you look back over, not a claim that each action continued throughout it.

Past perfect or past simple with when?

Compare an event already completed with an event at or just after the other past event. Tense can change the sequence you understand.

Cambridge explains that two past-simple clauses with when can place events at the same time or closely together. Do not teach 'the first verb in the sentence always happened first'. Clause order and event order are different things.

You do not need a past perfect for every past event

The past perfect is not a special tense for very old history. An ordinary past-simple statement can describe a distant time.

• The village built its first bridge in 1826.

A story can also give events in time order with the past simple. You do not have to put its first event into the past perfect just because another event comes later.

• I folded the map, put it away and walked to the platform.

Use the past perfect when you look back from a later past point. That point need not be in the same sentence: it may already be clear in the surrounding story.

• The studio was empty at five. Everyone had gone to the exhibition.

Five o'clock is the past viewpoint. Going to the exhibition explains the empty studio. The past perfect is not an isolated statement with no past viewpoint here.

Before and after: choices, not bans

Before and after can make the order clear. You can use past simple for both events, or use the past perfect to emphasise the earlier period. Neither form is automatically wrong.

• After Jo measured the shelf, she ordered the wood.
• After Jo had measured the shelf, she ordered the wood.

In both sentences, measuring comes before ordering. The second explicitly looks back at the completed measuring. Cambridge University Press's grammar presentation supports this choice with before and after.

Be careful with before + past perfect. British Council also uses it for an action not yet done or not complete when another past event happened.

• The taxi arrived before I had fastened my shoes.

Fastening was not complete at the taxi's arrival. This does not say the fastening happened first. Read the whole time relationship, including before; do not mechanically call every past-perfect event 'the first finished action'.

Experience and repeated events up to then

Like the present perfect, the past perfect can report experience or count earlier occasions. The difference is the viewpoint: then rather than now.

• It was the brightest comet I had ever seen.
• Before that weekend, Amir had never used a telescope.

Ever means at any time before that past point; never means at no time before it. The project or weekend gives the limit, not the moment when you are speaking now. A past-perfect experience does not mean you never repeated it later.

States and duration up to a past point

Use for with a length of time and since with a starting point. The past perfect can show a state or situation continuing up to the past point.

• When the shop closed in 2018, we had owned it for nine years.
• I had known Bea since childhood when we became business partners.

Knowing someone and owning something are states in these meanings. Use the simple perfect, not a continuous form, for these state meanings. See State verbs and action verbs.

Do not assume that every situation ended at the past viewpoint. The tense itself looks back to then. The context tells you whether the situation continued later: knowing Bea could continue after becoming partners.

For an activity continuing over time, the past perfect continuous can focus on duration: We had been sorting photographs for hours when the lights failed. See The past perfect continuous for the full contrast. For or since does not choose the simple or continuous by itself.

Reasons and background

An earlier event can explain a later past situation.

• The printer was silent because someone had unplugged it.

Unplugging came before the printer's being silent. The past perfect connects that earlier event to the later situation. The reason is not a new event happening after the silence.

You can also put earlier background into a relative clause, a clause describing a person or thing.

• We thanked the neighbour who had watered our plants.

Watering happened before the thanks. The clause beginning who identifies the neighbour and gives that earlier background. See Defining relative clauses: who, which, that for the clause pattern.

Earlier plans that changed

The past perfect can describe an earlier plan or intention which later changed. The later clause or context shows what changed.

• We had planned a picnic, but the park was closed.
• Lina had wanted a large workshop, but she chose a small studio instead.

Had planned alone does not mean 'the plan failed'. Here the contrast with but and the later information show the change.

Already, just, never and had had

Adverbs such as already, just and never can go between had and the participle. Already points to completion before the past point; just means a very short time before it.

• By the time I called, Noor had already sent the parcel.
• We had just sat down when the music began.

A time word is a clue to meaning, not a rule that forces the past perfect without a past viewpoint.

Had had is possible. The first had makes the perfect; the second is the participle of the main verb have.

• I wasn't hungry at three because I had had a late lunch.

Do not delete one had just because the words repeat. Here lunch happened before the later lack of hunger.

Reported speech and imagined past

In a report with a past reporting verb, past simple or present perfect can shift to past perfect. The change depends on the report's viewpoint; this is not a command to change every verb in every report.

• Nia said she had posted the invitation. looking back from what Nia said

See Reported statements: tense changes and say or tell and Reported questions and requests for the choices and exceptions.

The past perfect also appears in an if-clause imagining a different past: If I had saved the file, I wouldn't have lost the changes. See The third conditional: unreal past situations and Wish and if only: wishes about now, the past and the future; do not use these examples as ordinary time-sequence rules.
