What Is the Past Continuous Tense?
The Past Continuous Tense, also known as the Past Progressive Tense, is used to describe actions that were happening at a specific moment in the past. Unlike the Past Simple, which tells us that an action started and finished, the Past Continuous tells us that an action was in progress — it was ongoing, unfinished, and happening around a particular time. Think of it as a photograph of an action that was already happening when we looked at it.
We use this tense to paint a picture of the past, to set the scene in a story, and to show that two or more events were happening at the same time. It is one of the most important tenses for storytelling in English, because it gives the reader or listener a sense of being right in the middle of the action.
The Past Continuous is formed with the past tense of the verb be (was/were) followed by the -ing form of the main verb. This simple combination allows us to express a wide range of ideas about past events that were in progress.
When Do We Use It?
The Past Continuous Tense has several distinct uses. Each one helps us describe a different type of situation in the past. Understanding these uses is the key to mastering this tense.
| Use | Explanation | Example |
|---|---|---|
| Action in progress at a specific past time | Something was happening at a particular moment | At 9 o'clock last night, I was reading a book. |
| Interrupted action | A longer action was in progress when a shorter action interrupted it | She was walking to school when it started to rain. |
| Parallel actions | Two or more actions were happening at the same time | While he was cooking, she was setting the table. |
| Atmosphere / scene setting | Describing the background scene in a story | The sun was shining and the birds were singing. |
| Repeated annoying action | With "always" to express irritation about a past habit | He was always losing his keys. |
When you read novels or watch films, notice how the Past Continuous is used to describe what was happening in the background: "It was raining. People were hurrying along the street. A dog was barking somewhere in the distance." These sentences create the atmosphere before the main action begins.
Affirmative Sentences
To form affirmative sentences in the Past Continuous, we use the past tense of be (was or were) followed by the -ing form of the main verb. The choice between was and were depends on the subject.
Subject + was/were + Verb-ing
| Subject | Was / Were | Verb-ing | Full Sentence |
|---|---|---|---|
| I | was | studying | I was studying for the exam. |
| He | was | playing | He was playing the guitar. |
| She | was | writing | She was writing a letter. |
| It | was | raining | It was raining heavily. |
| You | were | listening | You were listening to music. |
| We | were | travelling | We were travelling through Paris. |
| They | were | waiting | They were waiting at the airport. |
Use was with I, he, she, and it. Use were with you, we, and they. This is the same rule as the Past Simple of "be".
Negative Sentences
To form negative sentences, simply add not after was or were. In spoken and informal English, the contracted forms wasn't and weren't are very common.
Subject + was/were + not + Verb-ing
| Subject | Full Form | Contracted Form |
|---|---|---|
| I | I was not sleeping. | I wasn't sleeping. |
| He | He was not listening to me. | He wasn't listening to me. |
| She | She was not working yesterday. | She wasn't working yesterday. |
| You | You were not paying attention. | You weren't paying attention. |
| We | We were not watching TV. | We weren't watching TV. |
| They | They were not running in the park. | They weren't running in the park. |
Be careful with contractions. Was not becomes wasn't, and were not becomes weren't. Do not mix them up:
✘ I weren't sleeping.
✔ I wasn't sleeping.
✘ They wasn't running.
✔ They weren't running.
Question Sentences
To form questions in the Past Continuous, move was or were to the beginning of the sentence, before the subject. For information questions, place the question word (what, where, why, etc.) before was/were.
Was/Were + Subject + Verb-ing?
Wh- + was/were + Subject + Verb-ing?
| Type | Question |
|---|---|
| Yes/No | Was she reading a book? |
| Yes/No | Were they playing football? |
| Yes/No | Was it snowing in London? |
| What | What were you doing at 8 o'clock? |
| Where | Where was he going when you saw him? |
| Why | Why were they shouting? |
| Who | Who was she talking to on the phone? |
One of the most frequently asked questions in the Past Continuous is: "What were you doing at...?" This is a natural way to ask about someone's activity at a specific past moment. You will hear it often in everyday conversation.
Spelling Rules for -ing
Adding -ing to a verb is usually straightforward, but there are some important spelling rules you need to follow. These rules apply to the Past Continuous as well as to every other tense that uses the -ing form.
| Rule | How It Works | Examples |
|---|---|---|
| Most verbs | Add -ing directly | play → playing, read → reading, eat → eating |
| Silent -e | Drop the -e, then add -ing | make → making, write → writing, dance → dancing |
| One vowel + one consonant | Double the consonant, then add -ing | run → running, sit → sitting, stop → stopping |
| -ie ending | Change -ie to -y, then add -ing | die → dying, lie → lying, tie → tying |
| -ee ending | Add -ing directly (do not drop the -e) | see → seeing, agree → agreeing, flee → fleeing |
| -l ending (British English) | Double the -l, then add -ing | travel → travelling, cancel → cancelling |
If the verb ends in two consonants, or if it has two vowels before the final consonant, do not double the last letter:
✔ help → helping (two consonants: lp)
✔ rain → raining (two vowels: ai)
✘ help → helpping
✘ rain → rainning
The Past Continuous does not simply tell us what happened — it places us inside the moment, showing us the world as it was unfolding.

Time Expressions
Certain time expressions are commonly used with the Past Continuous Tense. These words and phrases help signal that an action was in progress at a particular time or alongside another event.
| Time Expression | Function | Example |
|---|---|---|
| at 8 o'clock | Specific time in the past | At 8 o'clock, I was having breakfast. |
| when | Interrupted action (+ Past Simple) | I was reading when the doorbell rang. |
| while | Parallel actions (+ Past Continuous) | While I was cooking, he was cleaning. |
| as | At the same time as (similar to "while") | As she was leaving, she noticed the letter. |
| all day / all morning / all evening | Duration throughout a period | It was raining all day yesterday. |
| at that moment | Specific point in the past | At that moment, everyone was looking at her. |
| yesterday at (time) | Specific past time reference | Yesterday at noon, we were flying over Paris. |
When is usually followed by the Past Simple (the short, interrupting action): "I was sleeping when the alarm went off."
While is usually followed by the Past Continuous (the long, ongoing action): "While I was sleeping, the alarm went off."
Both sentences describe the same situation, but the structure changes depending on which word you use.
Short Answers
When answering yes/no questions in the Past Continuous, we use short answers with was/were. We do not repeat the full verb in the answer.
| Question | Positive Short Answer | Negative Short Answer |
|---|---|---|
| Was I talking too loudly? | Yes, you were. | No, you weren't. |
| Was he working? | Yes, he was. | No, he wasn't. |
| Was she crying? | Yes, she was. | No, she wasn't. |
| Was it snowing? | Yes, it was. | No, it wasn't. |
| Were you sleeping? | Yes, I was. | No, I wasn't. |
| Were we going the right way? | Yes, we were. | No, we weren't. |
| Were they waiting for us? | Yes, they were. | No, they weren't. |
Short answers use only was/were (or wasn't/weren't). Do not repeat the -ing verb:
✘ Yes, I was sleeping. (This is a full answer, not a short answer.)
✔ Yes, I was. (This is the correct short answer.)
Past Continuous vs Past Simple
One of the most important things to understand about the Past Continuous is how it differs from the Past Simple. These two tenses often appear together in the same sentence, and knowing when to use each one is essential for clear and accurate English.
| Feature | Past Continuous | Past Simple |
|---|---|---|
| Usage | Action in progress (background) | Completed action (main event) |
| Structure | was/were + Verb-ing | Verb-ed / irregular form |
| Signal Words | while, as, at that moment, all day | yesterday, last week, ago, in 2020 |
| Duration | Ongoing, unfinished at that time | Finished, complete |
| Example | I was walking in the park. | I walked to the park. |
| Together | I was walking in the park when I found a wallet. | |
In many sentences, the Past Continuous and Past Simple appear together. The Past Continuous describes the longer background action, and the Past Simple describes the shorter action that interrupts it. Think of the Past Continuous as the movie playing in the background, and the Past Simple as the event that suddenly happens on screen.
When two actions happen in the past and one interrupts the other, always use the Past Continuous for the longer action and the Past Simple for the shorter, interrupting action:
✔ While I was cooking, the phone rang.
✘ While I cooked, the phone was ringing.
The cooking was already in progress. The phone call interrupted it.
