Simple Past (in depth)

Learn to place a past event yesterday, in the previous week, at a distance from now, in a particular year or within a past stage of life. A time expression explains when something happened; it is not an automatic instruction to choose one tense.

Time expressions with Past Simple: when exactly did it happen?

1. First the event, then its place in time

Imagine a calendar entry: the event has already happened, and you describe it as a past fact. Past Simple provides that perspective, while yesterday, last week or in 2020 helps the listener locate it in time. Its consequences may still matter now: a lamp bought yesterday may still be on the desk.

Not every Past Simple sentence needs its own time expression. If the time is already clear from a question or previous remark, you need not repeat it. A time expression can also provide the frame for several following sentences.

How to build it

Who + Past Simple action + when. / When, + who + Past Simple action.

We bought a desk last month.

We bought a desk last month.

The purchase is presented as a past event; last month identifies the previous calendar month.

What did you do yesterday? — I repaired a chair.

What did you do yesterday? — I repaired a chair.

The answer has no yesterday, but the question has already established that time frame.

2. Yesterday and last: the previous day or period

Yesterday means the previous calendar day. Yesterday morning, yesterday afternoon and yesterday evening specify a part of that day. Last night often refers to the previous night or evening.

Last week, last month and last year mean the week, month and year before the current one. Last Monday refers to the previous Monday. In these expressions' usual meaning, do not put on/in/at or the before last: We met last week.

This rule applies specifically to those time expressions. In the last week can mean during the seven days up to now, while in the last week of June means during June's final week. These are different constructions, not errors simply because they contain in or the.

How to build it

yesterday (+ morning / afternoon / evening); last + night / week / month / year / Monday

The bus arrived late last night.

The bus arrived late last night.

Last night is already a time expression; it does not need at before it.

I checked the address yesterday morning.

I checked the address yesterday morning.

Yesterday morning is one clear time phrase without in.

We closed the shop in the last week of June.

We closed the shop in the last week of June.

The last week of June names the final part of a particular month, not simply last week.

3. Ago: count back from the time of speaking

Two hours ago measures two hours backwards from the moment someone speaks. Name the length of time first, then add ago: a minute ago, three days ago, a year ago. For an approximate distance, say about a month ago or a long time ago.

Yesterday names a day, while one day ago expresses a distance in time. They refer to the same day in many conversations, but are not equally precise: yesterday could have been a few hours or more than twenty-four hours ago. If exact timing matters, specify a time and date; do not combine them into yesterday ago.

When the reference point is another event rather than now, before is often needed: two days before the trip. This is a brief boundary note: the lesson practises ago measured from speaking time, not every way of narrating from a past reference point.

How to build it

length of time + ago

The lesson ended ten minutes ago.

The lesson ended ten minutes ago.

If it is 14:30 now, this refers to 14:20 on the same day.

We moved here about a year ago.

We moved here about a year ago.

About avoids pretending to give an exact date; ago stays after the length of time.

I packed my bag two days before the trip.

I packed my bag two days before the trip.

The trip is the reference point here. This is not necessarily two days before today, so ago is not a direct replacement.

4. In + year and when + a past stage of life

Use in for a calendar year: in 2018. For the year to be past in a particular account, it must precede that account's speaking time. The named date does not change from day to day, unlike yesterday or last year.

Sometimes an exact date is unnecessary: when I was a child, when we were students, when she was younger. The when-clause establishes a clear past frame. Within it, you can name a single event or an action that was habitual then; there is no need to invent a birth year or personal details.

How to build it

in + a past year; when + I/he/she was … / you/we/they were …

The café opened in 2016.

The café opened in 2016.

A year in this time expression requires in, not at or on.

When we were students, we cooked together.

When we were students, we cooked together.

The student years provide the past frame. The sentence does not require a particular calendar date.

5. Positioning the expression and asking about time

A time expression often comes at the end of a sentence. It can also come first to establish the frame: Last year, we changed our plans. This does not change the event's date. If an exercise asks for a particular position, that is a learning constraint, not a ban on other natural positions in English.

The time phrase remains in negatives and questions. After did/didn't, an ordinary verb takes the base form: Did you arrive yesterday? When used with be requires was/were, not did be. The short question When did it happen? helps you find out a time you do not yet know.

Last year, we changed our plans.

Last year, we changed our plans.

We changed our plans last year is equally natural. Initial position simply foregrounds the time.

Did you send the form two days ago?

Did you send the form two days ago?

Did is followed by send; two days ago does not change because the sentence is a question.

I didn't work yesterday.

I didn't work yesterday.

The negative concerns an event yesterday; didn't requires work.

6. A time expression is not a magic tense selector

Yesterday and last night are compatible with more than Past Simple. Past Continuous, for example, presents an action in progress at a particular past moment. First establish what the speaker describes: a past fact, an ongoing action or another time relationship. The main target here is a past fact with a suitable time expression.

Today and this morning are not automatically present or past markers. At 18:00, the morning is over, so a completed morning event can be described in Past Simple. Even while the day continues, an individual event can be presented as a past fact: I paid at nine today. A summary up to now may take a different perspective. Do not choose the tense from today alone.

For your own message, make three decisions: what happened, when it happened and whether the listener needs that time detail. Do not repeat a marker in every sentence when the frame is already clear.

At eight yesterday, I was cooking.

At eight yesterday, I was cooking.

Yesterday is correct here even though was cooking is Past Continuous: the sentence describes an action in progress at that moment.

I fixed the light this morning.

I fixed the light this morning.

Imagine an evening report about a completed repair. This morning works with Past Simple.

I paid at nine today.

I paid at nine today.

The speaker is talking after nine about a particular completed payment; an unfinished calendar day does not rule out Past Simple.

Common mistakes

Incorrect:I cleaned the kitchen yesterday ago.

Correct:I cleaned the kitchen yesterday.

Yesterday alone is enough to refer to the previous day. Ago combines with a length of time, not with the name of yesterday.

Incorrect:We arrived on last Friday.

Correct:We arrived last Friday.

In its usual meaning, last Friday does not need on. This does not prohibit on with other day expressions: on Friday is correct.

Incorrect:They called ago two hours.

Correct:They called two hours ago.

Ago follows the measured interval: two hours ago. Changing the order repairs the form without changing the time of the call.

Incorrect:The library opened at 2017.

Correct:The library opened in 2017.

Use in before a calendar year in this type of time expression.

Incorrect:Did you left yesterday?

Correct:Did you leave yesterday?

Yesterday locates the event in the past but does not override question structure: did requires the base form leave.

Irregular verbs: recalling and using V2

1. An irregular verb is not an error: it has a special form

V1 is the base form found in a dictionary: buy, go, make. V2 is the Past Simple form: bought, went, made. ‘Irregular’ means that these verbs do not form the required past tense simply by adding -ed. The words themselves are entirely correct and very common.

In an ordinary affirmative statement about a completed past event, put V2 after the subject. First identify what happened, then recall the form of the verb you need. A purchase remains a purchase: buy changes to bought, but the meaning of the message stays the same.

Here, the main focus is practising the form within a sentence. An exercise that supplies buy checks whether you can recall bought, rather than choose the verb or tense independently. Later, that support will be removed and you will choose the words for your own account.

How to build it

Subject + V2 + rest of the message: We + made + lunch.

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
V2 / past form
—
The form used in a Past Simple statement: worked, went, saw.

I bought a desk on Saturday.

I bought a desk on Saturday.

Buy requires the learned form bought; do not add -ed.

We made lunch together.

We made lunch together.

Made is the V2 form of make. The time may be understood from the conversation, even without yesterday.

2. Groups support memory; they do not generate new forms

It helps to learn small sets of verified forms. Vowel changes: sing → sang, drink → drank, swim → swam. Shared -ought spelling: buy → bought, bring → brought, think → thought. Forms ending in -t: keep → kept, sleep → slept, feel → felt; send → sent, spend → spent. Learn the specific pairs in each set.

These are not productive rules. Sing and bring look similar, but their past forms belong to different sets: sang and brought. Similarity helps you retrieve a word you have already learned, not guess an unknown form. If you are unsure, check the particular verb in a dictionary.

Some forms are easier to remember as individual pairs: go → went, have → had, do → did, make → made, take → took, see → saw. You do not have to fit every word into one neat pattern. A short sentence is often a better memory cue than a long list.

Our guest brought some fruit.

Our guest brought some fruit.

Recall bring → brought alongside bought and thought, but do not apply the sing → sang change to bring.

I kept the receipt and sent a copy to the office.

I kept the receipt and sent a copy to the office.

Kept and sent end in -t, but their internal changes differ: keep → kept, send → sent.

3. An unchanged form does not necessarily mean present time

Put → put, cut → cut, hit → hit and cost → cost, meaning ‘have a price’, change neither spelling nor pronunciation. Yet they can describe the past. Look at the whole sentence and situation instead of treating -ed as a compulsory sign of past time.

Read is different: its spelling stays the same, but V1 is pronounced /riːd/ and V2 /red/. The written answer read alone does not show how someone pronounces it. To identify the tense in a short written example, you need context; to check the sound, you need to hear the pronunciation.

Compare the habit I put my keys here every day with the completed event I put my keys here last night. Put has the same form, but the message differs. The isolated written word read, without context, does not reliably tell you whether it is V1 or V2.

The ticket cost ten euros last year.

The ticket cost ten euros last year.

Cost expresses a past price; its unchanged form does not make the sentence present tense.

I read the instructions before yesterday’s lesson.

I read the instructions before yesterday’s lesson.

This describes completed reading. Here, read is pronounced /red/, although it is spelled like the base form.

4. The second and third forms occupy different columns

Tables often have three columns: V1, V2 and V3. V3 is called the past participle. A simple affirmative statement in the Past Simple specifically requires V2: go — went — gone; see — saw — seen; swim — swam — swum.

For some words, V2 and V3 are identical: buy — bought — bought, send — sent — sent. This does not mean the third form can always replace the second. I saw the sign requires saw. Seen is used, for example, in have seen, a construction studied separately in more detail.

You do not need to build every tense with V3 now. Simply avoid taking the form from the neighbouring column when recalling a form for a completed event. Swam and swum differ in both pronunciation and spelling; the choice is not arbitrary.

They went to the market after breakfast.

They went to the market after breakfast.

Went is the V2 form of go. Gone is not a standalone past-tense form in this kind of statement.

She swam for twenty minutes.

She swam for twenty minutes.

The completed swim is described with swam, the second form of swim.

I have seen that sign before.

I have seen that sign before.

This is only a contrast: have is followed by V3 seen in this construction. It is not the pattern for a Past Simple affirmative statement.

5. Person does not change V2, but be has two forms

In ordinary affirmative statements, the same V2 form works with I, you, she, he, it, we and they: I took, she took, they took. Do not add the -s familiar from the present-tense form she takes.

An important exception is be: I/he/she/it was, you/we/they were. This does not mean bought or went should change according to the subject. Be has its own system; recognising that boundary is enough for this lesson.

Another boundary concerns did and didn’t. In an ordinary question or negative statement with did, the main verb returns to V1: Did you take it? I didn’t take it. Did already expresses past tense. The full construction of questions and negatives is practised under a separate rule; here, the aim is simply to avoid using V2 where it is not needed.

I had breakfast at seven. She had breakfast at eight.

I had breakfast at seven. She had breakfast at eight.

Had does not change with a different subject; only the breakfast time differs.

I was tired, but they were ready.

I was tired, but they were ready.

Be requires was or were depending on the subject.

I bought a bag, but I didn’t buy a coat.

I bought a bag, but I didn’t buy a coat.

Use bought in the affirmative statement and buy after didn’t. The verb’s irregularity does not remove this distinction.

6. Two standard variants are not an error

Some verbs have two acceptable past forms: learned/learnt, burned/burnt, dreamed/dreamt. Learned is used in both British and American English; learnt is characteristic of British English. A regional preference does not make another standard variant grammatically incorrect.

Another example is dive: dived, and also dove in American English. This illustrates a limit of the classification, rather than adding a compulsory list to memorise. If an exercise does not request a particular variant, standard alternatives should be accepted.

Do not change learned to learnt simply because the lesson is about irregular verbs. First ask whether the form is actually nonstandard or merely another acceptable variant. If an exercise explicitly requires the -t form, learned will not meet that learning requirement, but it remains a correct word in its own right.

I learned to use the new machine last week.

I learned to use the new machine last week.

Learned is correct; learnt is also possible without changing the meaning.

I burnt the toast this morning.

I burnt the toast this morning.

Burnt and burned are both acceptable in an account of this completed event.

7. The message establishes the time, not a magic word

A finished episode is useful for recalling V2: yesterday’s journey, the last meeting or a previous work shift. But yesterday is not a mechanical instruction determining every construction in a sentence. This lesson explicitly supplies a completed event and an ordinary affirmative statement so that attention stays on the verb form.

The question may already establish the time. A natural answer to What did you do after lunch? is I wrote two emails, without repeating a date. At the same time, a correct form alone does not guarantee the correct meaning: using wrote instead of read changes the action.

You do not need to put an irregular verb in every sentence of your own account. What matters is a clear event, suitable words and correct forms. Regular verbs, descriptions of the place and brief evaluations can naturally contribute to the account.

We met outside the station. Then we walked to the café.

We met outside the station. Then we walked to the café.

Met is an irregular V2 form; walked is a regular -ed form. They combine naturally within one episode.

I wrote two emails after lunch.

I wrote two emails after lunch.

Wrote specifically expresses writing the emails. Saw and read are also past forms, but would describe different actions.

8. Bringing the table into your own speech

Start with a few words you need. Cover the past forms and try to recall them from the base forms; check only after making an attempt. Then use each form in a small real or imagined event. Change the situation next time so that you are not simply repeating one memorised sentence.

Self-checking involves three questions: have I conveyed the intended fact, have I chosen V2 of the actual verb I need, and have I avoided putting V2 after did or in place of another required form? For read, also check the pronunciation in a dictionary: /red/ in the past. Written text alone does not prove correct pronunciation.

In open exercises, the model is one possible answer, and the criteria help you check your own. Another natural wording is allowed if it preserves the meaning and explicitly stated learning requirements. Self-assessment here is not an AI examiner’s verdict, an independent editorial review or confirmation of A2 proficiency.

I lost my ticket, so I bought another one.

I lost my ticket, so I bought another one.

The two forms support a clear ‘problem — action’ connection: lose → lost, buy → bought.

A neighbour found my keys and gave them back to me.

A neighbour found my keys and gave them back to me.

Found and gave are used in a new situation; the aim is to recall the forms rather than repeat a row of the table.

Common mistakes

Incorrect:I buyed a lamp yesterday.

Correct:I bought a lamp yesterday.

The V2 form of buy is bought. Regular -ed does not produce a standard past form of this verb.

Incorrect:She brang the keys.

Correct:She brought the keys.

Standard English requires brought. The sing → sang pattern does not extend to the similar-looking word bring.

Incorrect:We seen the new office on Monday.

Correct:We saw the new office on Monday.

An ordinary Past Simple affirmative statement needs V2 saw, not V3 seen.

Incorrect:He cutted the bread into small pieces.

Correct:He cut the bread into small pieces.

Cut has the unchanged V2 form cut. Adding -ed produces the nonstandard form cutted, not a missing marker of past tense.

Incorrect:They didn’t went to the meeting.

Correct:They didn’t go to the meeting.

After didn’t, use the base form go; the auxiliary already expresses past tense.

Incorrect:She tooks the early train.

Correct:She took the early train.

Do not add -s to V2 took after she. Agreement in takes belongs to the present tense, not this past form.

Past simple: negatives and questions without marking the past twice

1. Mark past tense once

In an ordinary affirmative, the main verb has a past form: worked, bought, went. In a question or negative with an ordinary verb, did carries past tense. The main verb therefore returns to its base form without to: work, buy, go.

Did is the same with I, you, he, she, it, we and they. Do not add -s with he/she/it, or retain -ed or an irregular past form after did. Compare the complete construction rather than only its final word.

How to build it

She bought a ticket. → She didn’t buy a ticket. → Did she buy a ticket?

He cleaned the kitchen. He didn't clean the bathroom.

He cleaned the kitchen. He didn't clean the bathroom.

The second sentence contains didn’t, so clean has no -ed. The negation concerns cleaning the bathroom, rather than the whole day.

Did they find the address?

Did they find the address?

Even an irregular verb needs find rather than found: did already marks the past.

2. Negate the fact you intend

Did not and didn’t express the same negation. The contraction is common in conversation; the full form is also correct and can emphasise the negative. Both follow the subject and precede a base verb.

Negation does not create new facts. I didn’t leave at six says there was no departure at six; I may have left earlier, later or not at all. It does not automatically mean staying all day. Likewise, didn’t buy does not mean didn’t have: something could have been a gift.

How to build it

Subject + did not / didn’t + base verb + remaining information.

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.
V1 / base form
—
The base verb without to: work, go, be.

We didn't order lunch yesterday.

We didn't order lunch yesterday.

The negation concerns ordering. The sentence does not establish whether they obtained lunch another way.

I did not leave at six. I left at seven.

I did not leave at six. I left at seven.

The second fact is compatible with the first, but must be stated separately rather than assumed.

3. A neutral question about a past action

To ask directly and neutrally whether an action occurred, place did before the subject and a base verb after it. For a specific detail, add when, where, why, how or another question word at the beginning.

Choose the question word for the missing detail: when for time, where for place, what for a thing or action, and who for a person. Preserve known participant roles: if Ava met Ben, a question about Ben still keeps Ava as the person who did the meeting.

How to build it

Did + subject + base verb? / Question word + did + subject + base verb?

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.
verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.
V1 / base form
—
The base verb without to: work, go, be.

Did you save the file? Where did you save it?

Did you save the file? Where did you save it?

The first question checks the fact; the second asks the location. Both use save after did.

Who did Ava meet?

Who did Ava meet?

Ava is the known subject. Who replaces the unknown person she met, so use did + meet.

4. Be: was/were without did

To describe a past state, location or quality with be, use was/were. Put was/were before the subject in a question and add not for a negative. These ordinary past-simple be sentences do not need did.

Use was with I/he/she/it and were with you/we/they. Full was not / were not and contracted wasn’t / weren’t are valid. Distinguish state The shop was closed from event The shop closed. Were they tired? asks about a state; Did they work? asks about working.

How to build it

Was/Were + subject …? / Subject + was not / were not …

subject / S
—
The grammatical subject: who or what the clause is about; the verb agrees with it. In The book was written, the book is the subject, although someone else does the action.

Were you at home yesterday? No, I wasn't.

Were you at home yesterday? No, I wasn't.

The question uses were with you, while the self-referential reply uses was with I. Do not add did.

The café wasn't open on Monday. The staff didn't work that day.

The café wasn't open on Monday. The staff didn't work that day.

Wasn’t open describes the café’s state; didn’t work negates the staff’s action. The verb determines the pattern, rather than past time alone.

5. Who acted, or whom did someone meet?

In a neutral affirmative-form subject question, who or what occupies the performer’s position. The ordinary verb keeps its past form: Who called? What happened? No additional did is needed for that question.

Who called you? asks who phoned you. Who did you call? asks whom you phoned. These express different participant roles rather than interchangeable word orders.

Emphatic Who DID call? is possible when asking who actually did call, and is not ungrammatical. A negative subject question also needs did: Who didn’t call? asks for the person who did not phone.

Who opened the window?

Who opened the window?

The unknown performer is the subject, so the neutral form uses opened without did.

Who did you invite?

Who did you invite?

Performer you is known; the question asks about the invited person, so use did + invite.

Maya didn't bring the cups. So who DID bring them?

Maya didn't bring the cups. So who DID bring them?

Capitals show stress rather than compulsory spelling. Did adds emphasis and takes bring after it.

6. A short answer must preserve the fact

Reply to a did question with Yes, … did or No, … didn’t / did not. For was/were questions, repeat the appropriate be form. The pronoun depends on who is discussed: Did you …? → Yes, I did.

When or where usually needs a time or place rather than only yes/no. A didn’t question often checks an expectation or expresses surprise. In ordinary short answers, Yes, I did confirms the action happened; No, I didn’t denies it. Add a full factual sentence to avoid misunderstanding if useful.

Did they wait? No, they didn't.

Did they wait? No, they didn't.

The short reply retains they and negates waiting; repeating wait is unnecessary.

Didn't you pay yesterday? Yes, I did. I paid by card.

Didn't you pay yesterday? Yes, I did. I paid by card.

Payment happened, so the short answer is positive. The additional sentence makes the fact unambiguous.

7. Boundaries: have, statement questions and used to

For lexical have expressing possession, modern neutral usage is Did you have …? / I didn’t have … . Forms such as Had you any money? are also possible, particularly in more formal or older British English. Do not call them ungrammatical. Exercises targeting neutral did specify that form separately.

You went by bus? is a valid question using statement order to check, confirm a guess or express surprise. Did you go by bus? is an ordinary direct question with inversion. If the task requests a neutral inverted question, the first may fail the target while remaining grammatical.

Used to describes a former habit or state. Did you use to …? / didn’t use to … can appear alongside this topic, but does not replace a question about one event. Here we only distinguish their scope. Spelling variants, the relationship with the present and all nuances of negative questions need separate study.

Did you have a ticket when you arrived?

Did you have a ticket when you arrived?

Have expresses possession of a ticket; use have rather than had after did.

You went by bus? Did you go by bus?

You went by bus? Did you go by bus?

Both questions are possible. The first uses statement order and needs suitable context; the second is the neutral question pattern.

Did you drink tea at breakfast yesterday? Did you use to drink tea at breakfast?

Did you drink tea at breakfast yesterday? Did you use to drink tea at breakfast?

One question concerns yesterday’s event; the other a former habit. Adding use to changes the meaning.

8. Applying the construction to your own response

First decide which fact you negate or which detail is unknown. Check whether the verb is an ordinary action, be or part of a neutral subject question. Finally check participants, time and the form after did.

In open tasks, compose your own English sentence before comparing it with the sample and criteria. Different natural wording is valid if it preserves meaning and an explicitly requested form. Self-checking helps identify errors but does not automatically certify correctness or an overall A2 level. Invent situations if you prefer.

The parcel didn't arrive yesterday. Did you send it on Monday?

The parcel didn't arrive yesterday. Did you send it on Monday?

An established negative fact precedes a question about an unknown one. A missing parcel does not prove it was never sent.

Common mistakes

Incorrect:Did you went to the market?

Correct:Did you go to the market?

After did, use base form go. Went already carries past tense and cannot follow did here.

Incorrect:We didn't booked a table.

Correct:We didn't book a table.

Didn’t already marks past tense. Remove -ed from book while preserving the negation of the booking.

Incorrect:Did she has a ticket?

Correct:Did she have a ticket?

After did, use have with every subject, including she. Has does not fit the construction.

Incorrect:Did they were at home?

Correct:Were they at home?

In a location question with be, were itself precedes the subject. Do not add did.

Incorrect:I wasn't went to work.

Correct:I didn't go to work.

The intended negative concerns action go rather than a state expressed with be: use didn’t + go.

Incorrect:Where did she left the bag?

Correct:Where did she leave the bag?

Question word where does not cancel the base-form requirement after did: leave rather than left.
