Key Takeaways
  • The past continuous is formed with was/were + verb-ing.
  • It describes an action in progress at a specific moment in the past.
  • It is often interrupted by a shorter action in the past simple: I was cooking when he called.
  • Two past continuous actions can run in parallel: While I was reading, she was writing.
  • Stative verbs (know, like, want) are rarely used in the continuous form.

When you want to describe what was happening at a particular moment in the past — the background to a story, or an action that was interrupted — English uses the past continuous (also called the past progressive). It pairs naturally with the past simple to show how events relate in time. This guide explains how to form the past continuous, all of its main uses, and how to tell it apart from the past simple.

How to Form the Past Continuous

The structure is the past of be (was or were) plus the -ing form of the main verb.

The Structure

Subjectbe (past)verb-ing
I / he / she / itwasworking
you / we / theywereworking

Negative: was not (wasn't) / were not (weren't) + -ing. Question: Was/Were + subject + -ing? — Were you sleeping?

Why it matters: The past continuous lets you show that an action was ongoing rather than complete — a distinction the past simple cannot make on its own.

Interrupted Actions

The most common use is for a longer action that was in progress when a shorter action interrupted it. The longer action takes the past continuous; the interruption takes the past simple, usually with when.

I was cooking dinner when the phone rang.

They were watching TV when the lights went out.

Note the pattern: while usually introduces the longer (continuous) action, and when usually introduces the shorter (simple) one.

Parallel Actions

When two actions were happening at the same time, both can take the past continuous, often joined by while.

While I was reading, my sister was studying.

He was talking on the phone while he was driving.

Setting the Scene

In storytelling, the past continuous paints the background — the situation that was already underway — while the past simple delivers the main events.

The sun was shining and the birds were singing. Suddenly, a car stopped outside.

Pro tip: Notice how the continuous verbs describe the scene and the simple verb (stopped) moves the story forward. This contrast is the heart of English narrative.

Past Continuous vs Past Simple

Key Contrast

Past simplePast continuous
Completed actionAction in progress
I read a book. (finished it)I was reading a book. (in the middle)
When she arrived, I made tea. (after)When she arrived, I was making tea. (already in progress)

The choice changes the meaning: "When she arrived, I made tea" means you started after she came; "When she arrived, I was making tea" means you had already begun.

Stative Verbs

Verbs that describe states rather than actions — know, believe, like, love, want, understand, belong — are normally not used in the continuous. We say "I knew the answer", not "I was knowing the answer." A few of these verbs can take a continuous form with a different, action-based meaning ("I'm thinking about it"), but as states they stay simple.

Common Mistakes

The first common error is using was/were with the wrong subject — remember was for I/he/she/it and were for you/we/they. The second is forgetting the -ing and producing a plain past ("I was cook"). The third is using the continuous for short, complete actions where the past simple is correct. The fourth is using stative verbs in the continuous ("I was wanting"). Mastering the contrast with the past simple resolves most of these.

Frequently Asked Questions

How do you form the past continuous tense?
Use was or were plus the -ing form of the main verb. Use was with I, he, she and it, and were with you, we and they: "I was working", "they were working." The negative adds not (wasn't / weren't), and questions invert the order: "Were you sleeping?"
When do we use the past continuous?
Use it for an action that was in progress at a specific past moment. Common cases are interrupted actions ("I was cooking when the phone rang"), two parallel ongoing actions ("While I read, she studied"), and setting the background scene in a story before the main events happen.
What is the difference between the past simple and past continuous?
The past simple describes a completed action ("I read the book"), while the past continuous describes an action in progress ("I was reading the book"). The contrast matters: "When she arrived, I made tea" means you started afterwards, but "I was making tea" means you had already begun.
How do interrupted actions work with the past continuous?
The longer, ongoing action takes the past continuous and the shorter interrupting action takes the past simple, usually linked by when: "I was watching TV when the lights went out." The continuous shows the activity already in progress, and the simple shows the sudden event that interrupted it.
What is the difference between "when" and "while" here?
While usually introduces the longer action in the past continuous ("While I was reading..."), and when usually introduces the shorter action in the past simple ("...when the phone rang"). This is a guideline rather than an absolute rule, but it helps you choose the right tense for each clause.
Can two actions both be in the past continuous?
Yes. When two actions were happening at the same time, both can take the past continuous, often joined by while: "While I was cooking, she was setting the table." This shows the two activities overlapping in time rather than one interrupting the other.
Why can't I use stative verbs in the past continuous?
Stative verbs describe states rather than actions — verbs like know, believe, like, want and understand. These normally stay in the simple form: "I knew the answer", not "I was knowing the answer." A few can be continuous with an action meaning, such as "I'm thinking about it."
How is the past continuous used in storytelling?
It sets the scene by describing situations already underway: "The sun was shining and the birds were singing." The past simple then carries the main events forward: "Suddenly, a car stopped." This contrast between ongoing background and completed action is central to English narrative.
When should I use "was" and when "were"?
Use was with singular subjects I, he, she and it, and were with you, we and they. So it is "I was running" and "he was running", but "you were running" and "they were running." Matching the correct form of be to the subject is a common point to check.
How can I practise the past continuous?
