Past Continuous: building an action in progress in the past

1. Looking inside a past action

Imagine a snapshot of yesterday. The Past Continuous shows what was in progress at that moment: someone was cooking, waiting, or writing a message. We view the action from within rather than report its completed result.

The time can be stated in the sentence or already clear from the conversation. At nine is the point of observation, not necessarily the start or end of the action. The Past Continuous alone also does not tell us whether the situation is still true now.

How to build it

subject + was/were + verb with -ing

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.
V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

At nine last night, I was washing the dishes.

At nine last night, I was washing the dishes.

The washing was already in progress at nine; its finishing time is not stated.

What were you doing at noon? — I was having lunch.

What were you doing at noon? — I was having lunch.

The answer inherits the past time reference from the question. There is no need to repeat at noon.

I was living in Lviv then. I still live there.

I was living in Lviv then. I still live there.

The second sentence clarifies the present situation; the first focuses only on the past period.

2. Was or were: look at the subject

Use was with I, he, she, and it. Use were with you, we, and they. You were is correct even when addressing one person. They were remains correct when they refers to one person.

A singular noun usually takes was: the driver was. A plural noun takes were: the drivers were. In a longer noun phrase, identify the head: the woman with two bags refers to one woman, not two bags.

How to build it

I/he/she/it → was · you/we/they → were

You were waiting outside.

You were waiting outside.

There is one addressee, but the pronoun you requires were.

The woman with two bags was talking to the driver.

The woman with two bags was talking to the driver.

Was agrees with woman. Bags in the additional description does not determine the verb form.

A customer was waiting. They were looking at their phone.

A customer was waiting. They were looking at their phone.

The subject a customer first takes was, then the pronoun they takes were, even though both refer to the same person.

3. Do not lose half the construction

The Past Continuous contains at least two parts: was/were and an -ing form. In an affirmative sentence, was typing is one verb phrase. Typing alone, without was, does not form a complete past-tense sentence.

This construction requires an -ing form after was/were, not the base form or a past-tense form. When the subject changes, the -ing form stays the same: she was waiting → they were waiting.

The printer was working.

The printer was working.

Was places the description in the past; working shows an action in progress.

The printers were working.

The printers were working.

With a plural subject, was changes to were; working remains the same.

4. Spelling -ing without extra letters

Often, simply add -ing: work → working, play → playing. Final y remains: study → studying. In familiar verbs with a final silent e, drop it: write → writing, make → making.

In one-syllable verbs with one vowel letter before one final consonant, the consonant is often doubled: sit → sitting, run → running. Do not double w, x, or y: snowing, fixing, playing. The two vowel letters in wait mean no doubling is needed: waiting. The unstressed final syllable in open gives opening. Learn lie → lying separately.

I was writing an email.

I was writing an email.

Write loses its final e: writing, not writeing or writting.

We were sitting near the door.

We were sitting near the door.

Sit doubles t before -ing.

My keys were lying on the table.

My keys were lying on the table.

Lie, meaning be in a horizontal position, forms lying. A situation does not have to involve deliberate activity to be described as ongoing.

5. Negatives: not after was/were

To say that an action was not happening then, put not after was or were. The main verb retains -ing. Did is not needed for this negative.

Was not and wasn't, and were not and weren't, express the same negation. Contractions are common in conversation and informal writing; full forms are also correct, particularly for emphasis.

How to build it

subject + was/were + not + verb with -ing

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.
V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

I was not using your laptop.

I was not using your laptop.

The sentence denies using the laptop at an already established past moment.

They weren’t sleeping at seven.

They weren’t sleeping at seven.

Weren't combines were and not; sleeping stays unchanged.

6. Questions and short answers

In a standard yes/no question, move was/were before the subject. To ask about a place or activity, put where or what before the auxiliary. Do not add did when was/were is already present.

In a short answer, repeat the appropriate pronoun and was/were, not the whole action. One person answers Were you…? with Yes, I was; a group answers Yes, we were. Negative short answers can use was not/wasn't or were not/weren't.

If who is itself the subject, there is no separate you or he after it: Who was using the room? This asks which person was using it, not what the addressee was doing.

How to build it

Was/Were + subject + verb with -ing? · What/Where + was/were + subject + verb with -ing?

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.
V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

Were you carrying a bag? — Yes, I was.

Were you carrying a bag? — Yes, I was.

Were agrees with you in the question; was agrees with I in one person's answer.

Where was Marta waiting? — She was waiting upstairs.

Where was Marta waiting? — She was waiting upstairs.

Where comes before was; the subject Marta comes after was.

Was the light flashing? — No, it wasn’t.

Was the light flashing? — No, it wasn’t.

It replaces the light, and wasn't keeps the answer negative.

7. Limits: not every past sentence needs the Continuous

Presenting an action as in progress is a choice of perspective, not an automatic consequence of yesterday or at six. I worked yesterday and I was working at six yesterday can both be correct: the first reports work as a past fact, while the second shows it in progress at six.

State verbs such as know are not usually used in the Continuous in their ordinary meaning: I knew the address. Meaning matters more than a word list, however. I was thinking about the address describes a process of considering something; He was being rude describes behaviour at the time, so these forms are possible.

Combining an ongoing past action with another event, or describing two parallel actions, comes in later topics. Here, focus on reliably building one construction. When and while are not commands that always determine the tense by themselves.

I knew the address, but I was checking the bus times.

I knew the address, but I was checking the bus times.

Knowing is a state; checking is an activity in progress. There is no need to put both verbs in the same form.

I was thinking about your question.

I was thinking about your question.

Thinking here means actively considering something, not holding a settled opinion.

He was being rude during the call.

He was being rude during the call.

This evaluates behaviour during that period, rather than identifying an unchanging personal trait.

8. Use the form in a short conversation

First establish the past time frame. Then decide what you need to do: describe an activity, correct an assumption, or clarify a detail. The subject determines was/were; your intention determines an affirmative, not, or question word order.

In your own answers, you can vary the words and the order of adverbials if the meaning stays the same. A model answer is a guide for checking your work, not the only permitted response. Real personal facts are unnecessary: an invented situation works just as well.

Were you driving at eight? — No, I wasn’t. I was waiting for a bus.

Were you driving at eight? — No, I wasn’t. I was waiting for a bus.

The answer first rejects the assumption, then gives the actual activity within the same past snapshot.

Common mistakes

Incorrect:She were cooking dinner.

Correct:She was cooking dinner.

In an ordinary description of a past action, she agrees with was.

Incorrect:You was waiting outside.

Correct:You were waiting outside.

You takes were even when it refers to one person.

Incorrect:I was wrote an email.

Correct:I was writing an email.

Wrote is a Past Simple form. After was, use writing to describe an action in progress.

Incorrect:They were not wait for us.

Correct:They were not waiting for us.

Negation does not remove -ing from the target construction.

Incorrect:Did she was working at noon?

Correct:Was she working at noon?

The question is formed by putting was before she; an additional did is unnecessary.

Incorrect:We were swiming near the shore.

Correct:We were swimming near the shore.

Swim doubles m before -ing: swimming. Swiming is incorrectly spelt.

Past Continuous with Past Simple: what was happening when something happened

1. Background and event: two perspectives on one story

Imagine a snapshot of the past. Something is already happening: a person is reading, waiting, or walking home. Another event occurs against this background. The Past Continuous gives the ongoing background, while the Past Simple reports the event as a fact.

The question is not simply which action is longer. What matters is how you present it: from within the process or as a whole event. In this lesson's typical sentence, the background action was already happening when the other event occurred.

How to build it

background: was/were + verb ending in -ing → event: Past Simple

verb / V
—
A word for an action or state, such as work or be. The pattern determines its form.
V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

I was reading a menu when the waiter arrived.

I was reading a menu when the waiter arrived.

The reading was already in progress; arrived reports the waiter's arrival.

We were walking to the station when we found a wallet.

We were walking to the station when we found a wallet.

Walking to the station provides the background to finding the wallet. The sentence does not state how many minutes we walked or when we reached the station.

2. Build each clause separately

For the background, use was with I/he/she/it and were with you/we/they. You takes were even when addressing one person; they also takes were when it refers to one person. An -ing form follows was/were.

An affirmative event clause needs a past form: arrived, dropped, found, took. In negatives and questions with did, the base form returns: did not arrive, Did you find…? In the Past Continuous, add not to was/were for a negative and put was/were before the subject for a question. Do not mix these two constructions.

How to build it

Past Continuous background + when + Past Simple event

You were carrying a bag when I saw you.

You were carrying a bag when I saw you.

Were agrees with you; saw is the past form of see.

We weren't sleeping when the rain started.

We weren't sleeping when the rain started.

The sentence denies sleeping at that moment, not the start of the rain. The full form were not is also correct.

Did you drop the cup while you were washing it?

Did you drop the cup while you were washing it?

The main question uses Did you drop, not Did you dropped. The clause while you were washing it retains statement word order.

3. When and while link times; they do not dictate forms

Start with two useful patterns: background + when + event; while + background, event. Both connect an event with an ongoing process. The when- or while-clause can come first; if it does, put a comma after it.

When can also introduce an ongoing process: I fell when I was running. While means during the time that, and it does not require only the Continuous either: simple forms are possible when actions are presented as whole events. Identify the intended meaning before choosing the forms.

While I was packing, a neighbour knocked on the door.

While I was packing, a neighbour knocked on the door.

The while-clause names the process; knocked reports an event during it.

A neighbour knocked on the door when I was packing.

A neighbour knocked on the door when I was packing.

When is followed by the Past Continuous here. This is a normal way to describe the background.

I washed the cups while Dan dried the plates.

I washed the cups while Dan dried the plates.

Both actions are presented as whole past activities. While does not make them ungrammatical or automatically require continuous forms.

4. Changing a tense may change the perspective, not correct an error

Compare the story, not just the verb endings. He was already cooking when I arrived differs from I arrived, and then he started cooking. For the second meaning, the Past Simple and then make the sequence explicit.

The Past Simple also fits a long activity when we report it as a whole. Three hours of work does not require the Continuous. The meaning of working alone does not determine one English tense without context.

When I arrived, Max was making tea.

When I arrived, Max was making tea.

Making tea was already in progress when I arrived.

I arrived, and then Max made tea.

I arrived, and then Max made tea.

Then explicitly establishes a different sequence. This is a correct sentence with a different intended meaning.

I worked for three hours yesterday.

I worked for three hours yesterday.

The period of work is presented as a complete fact, not as a snapshot within it. Worked three hours is also possible.

5. The event does not always stop the background activity

This pattern is often described as one action interrupted by another. Sometimes the activity really stops: a power cut, for example, can prevent reading. But the two tenses alone do not prove that the process ended. The event may simply happen during it.

Do not invent an exact beginning, ending, or cause. If it matters whether the person stopped or continued, say so explicitly. The Past Continuous describes a past time frame; it does not automatically establish that the situation is no longer true now.

I was drawing when a message arrived. I kept drawing.

I was drawing when a message arrived. I kept drawing.

The second sentence explicitly states that drawing continued. There is no contradiction.

We were having lunch when the alarm rang. We stopped eating.

We were having lunch when the alarm rang. We stopped eating.

We stopped eating reports the interruption; were having alone does not.

6. Ask about the background or the event

To find out what was already happening, ask What were you doing when…? To ask about the event, use What happened while…? These fill different gaps in the story.

In your answer, account for who is speaking: you in a question can become I in your response. Short answers such as Yes, I was or No, I wasn't are appropriate, but add what you were doing to practise storytelling. Different wording and natural clause orders are allowed when the meaning is preserved.

What were you doing when the bus arrived?

What were you doing when the bus arrived?

The question asks about the process at the moment of arrival, not an action afterwards.

I was checking the map when it arrived.

I was checking the map when it arrived.

I responds to you, and it refers to the bus already mentioned.

What happened while you were waiting?

What happened while you were waiting?

What is the subject of happened, so do not add did here. The question seeks information about an event.

7. Limits: states and two ongoing processes

Not every background situation needs the Continuous. States such as knew the answer usually take a simple form, even when they lasted. In this lesson, the main background is an observable action or activity: reading, waiting, walking.

Two Past Continuous forms are also possible if both actions are presented as ongoing. This is a different emphasis, not an automatic error. Here, the target is an ongoing process plus an event; two parallel actions form a separate topic. In open tasks, check your answer against the meaning, target perspective, and criteria: the model gives one option, not every correct sentence.

I knew the address when the driver asked me.

I knew the address when the driver asked me.

Knew describes knowledge, a state. Its role as background does not require a continuous form.

The phone was ringing while I was cooking.

The phone was ringing while I was cooking.

Both processes are presented as ongoing. To focus on the ring as an event, you can say The phone rang while I was cooking.

Common mistakes

Incorrect:I were opening a box when the bell rang.

Correct:I was opening a box when the bell rang.

In an ordinary past narrative, I takes was, not were.

Incorrect:She was wait when the taxi arrived.

Correct:She was waiting when the taxi arrived.

The Continuous requires waiting after was, not the base form wait.

Incorrect:Did you found the key while you were cleaning?

Correct:Did you find the key while you were cleaning?

Did already marks the past tense; use the base form find after it.

Incorrect:We didn't sleeping when the rain started.

Correct:We weren't sleeping when the rain started.

To negate the ongoing process, use were not / weren't + sleeping. Didn't does not combine with -ing as was/were does.

Two simultaneous actions in the past

1. Two actions in the same frame

Imagine a frame from yesterday: one person is cooking in the kitchen while another is washing dishes. When describing that past moment, we can present both actions as processes: was cooking and was washing. This is the main perspective in this lesson.

In its time meaning, while links things happening simultaneously. The sentence does not establish the exact beginnings and ends of both actions. They may have started and finished at different times; what matters is that they overlapped in the scene described. You do not need to imagine two actions of equal duration.

I was making soup while Dan was washing the dishes.

I was making soup while Dan was washing the dishes.

We see the cooking and washing in progress, rather than report that one finished before the other began.

At eight, the guests were chatting while the band was playing.

At eight, the guests were chatting while the band was playing.

Both actions were in progress at eight. The starting times of the conversations and performance are not stated.

2. Give each action its own correct form

Check the subject in each clause: I/he/she/it and one person or thing take was; you/we/they and several people or things take were. The auxiliary must be followed by an -ing form. Two different subjects cannot simply share one was or were across while.

Form negatives with was not / were not, also wasn’t / weren’t in ordinary speech. In a question, move was or were before the subject of the clause being asked about. The clause after while keeps ordinary word order.

How to build it

subject + was/were + -ing verb + while + subject + was/were + -ing 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.
V-ing / -ing
—
The verb form ending in -ing: working, going. Its role depends on the construction.

The driver was waiting while the passengers were getting on.

The driver was waiting while the passengers were getting on.

One driver → was; several passengers → were. Both actions are presented as ongoing.

I wasn't sleeping while you were talking.

I wasn't sleeping while you were talking.

Sleeping specifically is negated. Talking was in progress; the sentence does not say that sleeping also took place.

Were you drawing while Mia was reading?

Were you drawing while Mia was reading?

Were comes before you in the question, but after while the order Mia was reading does not change.

3. Where to put while

The while-clause can come first or after the main clause. If you start with While, a comma is usually needed after that clause. Reordering the clauses changes the presentation of information, but does not in itself make simultaneous actions sequential.

You can also express simultaneity with and plus at the same time. In exercises that explicitly specify while, practise that conjunction. This is a requirement of the particular exercise, not a claim that other ways to describe the scene are incorrect.

While Eva was painting the wall, Max was moving the chairs.

While Eva was painting the wall, Max was moving the chairs.

The While-clause comes first and ends with a comma.

Max was moving the chairs while Eva was painting the wall.

Max was moving the chairs while Eva was painting the wall.

The same processes and participants; this time we start with Max’s action.

Eva was painting, and Max was cleaning at the same time.

Eva was painting, and Max was cleaning at the same time.

And connects the messages; at the same time makes the time relationship explicit.

4. Is there a basis for claiming simultaneity?

Two statements about yesterday do not yet prove that the actions coincided. If all you know is that one person worked yesterday and another studied yesterday, do not automatically add while: that would introduce a new time relationship.

A shared moment, a description of a single scene or a known overlap between intervals provides a good basis. For example, one person worked from 10:00 to 10:30, another from 10:15 to 10:45. At 10:20 both were busy, although their starting and finishing times differed.

At 10:20, Lee was typing while Noor was packing boxes.

At 10:20, Lee was typing while Noor was packing boxes.

The shared moment falls within both specified work intervals. The sentence describes that moment, not each person’s entire working period.

I worked yesterday. My sister studied yesterday.

I worked yesterday. My sister studied yesterday.

Both sentences are correct, but they do not by themselves say whether our activities happened at the same time.

5. While and when do not choose the tense for you

Two Past Continuous forms clearly present two processes. However, while does not require the Past Continuous in every sentence. The Past Simple can present an event as a whole; changing the perspective does not always change the basic facts. A description of reading, watching or working does not by itself give one automatic tense choice.

When can mean “at the time that”, rather than introduce only a short event. An event against the background of an ongoing action often uses Past Simple + Past Continuous, but we identify this pattern by meaning, not by when alone. This lesson teaches you to build two processes specifically; an acceptable sentence with another perspective may fail to meet the learning target without becoming ungrammatical.

While I was watching the video, Jo was taking notes.

While I was watching the video, Jo was taking notes.

Both actions are presented as processes within a shared scene.

While I watched the video, Jo was taking notes.

While I watched the video, Jo was taking notes.

This sentence is also possible: watching is presented in the Past Simple. While alone does not make watched incorrect.

When I was working in the café, people were talking around me.

When I was working in the café, people were talking around me.

When establishes the time frame, and both clauses can use the Past Continuous.

While I was cooking, the doorbell rang.

While I was cooking, the doorbell rang.

The ringing is presented as an event against the background of cooking. These are not two ongoing processes, but the construction with while is entirely correct.

6. Two actions do not necessarily mean two people

One person can do two compatible things: listen and write, cook and talk. You can also combine a person’s activity with the weather or the operation of a device. Check that the scene itself is plausible.

Do not turn every verb into -ing just for symmetry. For example, know in the sense of possessing knowledge normally describes a state and does not need the continuous. If the meaning contains a state, do not force it into a second ongoing action; to practise this pattern, choose actions such as listening, writing and walking.

I was listening to the teacher while I was writing notes.

I was listening to the teacher while I was writing notes.

The same agent appears in both clauses; this does not remove simultaneity.

We were walking home while it was snowing.

We were walking home while it was snowing.

The people’s movement and the snowfall are presented as two processes.

I knew the song, and Eva was singing it.

I knew the song, and Eva was singing it.

Knew expresses knowledge, not an action in progress. The sentence is correct, although it is not the target pair of two continuous forms.

7. Using the pattern in a story

First choose a shared past moment. Then name two actions that were in progress and decide which to put first. Check was/were separately with each subject. You can use this to describe a photo, a work scene, a journey or an evening at home.

Not every sentence in a story needs to be continuous. Other constructions may be needed for a location, an evaluation, or the beginning or end of an event. In open-ended exercises, the model is just one option: compare the meaning, simultaneity and form with your answer, not every word in sequence.

It was a quiet evening. I was fixing my bike while my friend was reading on the balcony.

It was a quiet evening. I was fixing my bike while my friend was reading on the balcony.

The first sentence sets the scene; the second shows two processes. Invented stories work just as well as personal ones.

What were you doing while the others were setting the table?

What were you doing while the others were setting the table?

The question asks for a parallel activity, not the next event.

Common mistakes

Incorrect:While I were reading, Anna was drawing.

Correct:While I was reading, Anna was drawing.

When describing an actual past action with I, use was. The form in the second clause does not need changing.

Incorrect:We were cooking while Ben watching TV.

Correct:We were cooking while Ben was watching TV.

After while there is a separate subject, Ben, so its predicate needs its own was.

Incorrect:I was write notes while you were speaking.

Correct:I was writing notes while you were speaking.

After was, an action in progress needs writing, not the base form write.

Incorrect:Did you were working while Mia was resting?

Correct:Were you working while Mia was resting?

A Past Continuous question is formed by reversing were and you; an extra did is unnecessary.

Incorrect:They weren't play while we were studying.

Correct:They weren't playing while we were studying.

For a negated ongoing action in the Past Continuous, weren’t must be followed by playing, not the base form play.
