Choosing between worked and was working is not always obvious. Both can refer to the same past period, but they do not present the situation in the same way.
If you say I worked on the report at nine o’clock, you report the activity as part of the past. If you say I was working on the report at nine o’clock, you place yourself inside the activity while it was happening.
That difference matters far more than whether an action was “long” or “short.” The Past Continuous is mainly about how you view a past situation: as something already underway around a particular time or event.
What Is the Past Continuous Tense?
The verb tense Past Continuous, also called the Past Progressive, is formed with was or were followed by the -ing form of the main verb.
The research team was reviewing the evidence.
Several reporters were waiting outside the courthouse.
The tense presents a past activity or situation from inside its progress.
Compare:
At nine o’clock, Elena wrote the report.
At nine o’clock, Elena was writing the report.
The second sentence shows the writing as already underway at nine o’clock.
It does not tell us exactly when Elena started or finished.
How to Form the Past Continuous
Use:
was/were + verb-ing
Use was with I, he, she, it and singular subjects.
Use were with you, we, they and plural subjects.
Affirmative Sentences
Use:
subject + was/were + verb-ing
I was preparing the briefing notes.
The architect was examining the revised plans.
Several departments were sharing the same temporary office.
Negative Sentences
Put not after was or were.
subject + was/were + not + verb-ing
The finance team was not expecting another delay.
We weren’t using the main entrance that morning.
The servers weren’t responding properly.
The common contractions are:
was not → wasn’t
were not → weren’t
Yes/No Questions
Move was or were before the subject.
was/were + subject + verb-ing?
Was Maya waiting for the revised figures?
Were the engineers testing the backup system?
Wh-Questions
Put the question word before was or were.
What were you working on when I called?
Why was the company changing its pricing model?
Where were the delegates staying during the conference?
Short Answers
Repeat was or were, not the main verb.
Was Daniel working late?
Yes, he was.
Were they waiting outside?
No, they weren’t.
How to Add -ing to the Main Verb
Most verbs simply take -ing.
work → working
review → reviewing
discuss → discussing
Some need a spelling change.
Verbs Ending in Silent -e
Drop the final e.
write → writing
move → moving
prepare → preparing
Verbs That Double the Final Consonant
Some verbs double the final consonant before -ing.
run → running
sit → sitting
plan → planning
With longer verbs, stress often affects the spelling.
admit → admitting
prefer → preferring
but:
visit → visiting
Verbs Ending in -ie
Change ie to y.
lie → lying
die → dying
These are the same -ing spelling patterns used in other continuous forms.
When Do We Use the Past Continuous?
The Past Continuous appears in several kinds of past situations. What connects them is the way the speaker presents the activity, situation, or development.
1. An Activity in Progress at a Particular Past Time
Use the Past Continuous when you want to show what was happening around a specific point in the past.
At 7:30 yesterday evening, the design team was still discussing the final layout.
This time last Friday, we were flying over the Atlantic.
At noon, technicians were inspecting the damaged equipment.
The activity began before that reference point and continued through it.
The sentence does not necessarily tell us what happened afterward.
At ten o’clock, Amir was drafting the proposal.
He may have finished shortly afterward or much later. The sentence only tells us what was happening at ten.
2. An Activity Already Underway When Another Event Happened
The Past Continuous often shows what was happening when another past event occurred.
I was reviewing the contract when the client called.
The technicians were replacing a faulty component when the alarm sounded.
Nina was presenting the quarterly figures when the projector stopped working.
The activity in the Past Continuous was already underway before the Simple Past event happened.
The Second Event Does Not Have to Stop the First
This pattern is often described as an “interrupted action,” but that can be misleading.
I was walking through the lobby when I noticed the new exhibition.
Noticing the exhibition did not necessarily stop the walking.
Daniel was working from home when the company announced the merger.
His work may simply have continued.
The important relationship is that one situation was already happening when another event occurred.
3. Two Activities Happening at the Same Time
The Past Continuous can show that two activities overlapped.
While the legal team was checking the contract, the finance department was reviewing the projected costs.
I was taking notes while the panel was discussing the proposal.
Researchers were cataloguing the collection while conservators were restoring several damaged manuscripts.
Neither activity has to interrupt the other. Their time periods simply overlap.
4. Background in Stories and Past Accounts
The Past Continuous is useful for showing what was already happening around the main events of a story.
Rain was falling heavily, commuters were crowding beneath the station canopy, and traffic was moving slowly through the city centre.
That creates the setting.
The main events can then move forward in the Simple Past:
A bus stopped beside the entrance, and a woman stepped onto the pavement.
This background-versus-event contrast is one reason the two tenses often appear together in narratives.
5. Temporary Situations During a Past Period
The Past Continuous can describe a situation that was temporary or limited to a particular period.
During the renovation, staff were working from temporary offices.
Throughout the summer, the research team was collecting samples from several coastal sites.
At the time, the company was expanding rapidly across Southeast Asia.
The focus is on what was going on during that period.
A long situation does not automatically require the Past Continuous.
The company operated from that building for twenty years.
That sentence presents the whole period as a completed past fact rather than showing the situation from inside its development.
6. Repeated Activity During a Past Period
The Past Continuous can also describe repeated activity that formed part of an ongoing past situation.
During the final month of the project, we were meeting almost every evening.
The two departments were exchanging revised drafts several times a week.
That winter, I was travelling to Manchester every Monday.
Compare:
I travelled to Manchester every Monday for six months.
This reports the finished habit more neutrally.
That winter, I was travelling to Manchester every Monday.
This places more attention on the routine as part of that temporary past period.
7. Repeated Behaviour With Always, Constantly, and Similar Words
The Past Continuous can draw attention to repeated behaviour.
One supplier was always changing the delivery schedule at the last minute.
Our old printer was constantly jamming during busy afternoons.
Daniel was forever leaving confidential documents on his desk.
This pattern can express irritation, criticism, surprise, affection, or another attitude.
The words themselves do not automatically create a negative meaning. Context determines the speaker’s attitude.
8. Changes and Developments in Progress
The Past Continuous works naturally when something was gradually developing.
Demand for electric vehicles was increasing steadily.
The neighbourhood was becoming more expensive.
Her confidence was growing with every presentation.
Working practices were changing rapidly across the industry.
The speaker looks at the change while it was still unfolding rather than presenting it as a completed result.
Past Continuous With When and While
When and while often appear with the Past Continuous, but they do not choose the tense by themselves.
While Often Introduces an Ongoing Activity
While I was checking the figures, Sophie was preparing the presentation.
The lights went out while the technicians were testing the equipment.
Because while introduces a period of time, it often works naturally with an ongoing activity.
But it does not require two Past Continuous forms.
When Can Work With Different Past Forms
A common pattern is:
I was driving home when the storm began.
But when can also introduce a Past Continuous clause:
When I was working in Madrid, I often travelled by train.
Or it can connect two Simple Past events:
When the meeting ended, everyone left the room.
So rules such as “when = Simple Past” and “while = Past Continuous” are too rigid. The meaning of the clause matters more than the connector.
Past Continuous vs. Simple Past
The difference is not long action vs. short action.
Compare:
The committee discussed the revised proposal.
The committee was discussing the revised proposal when the chair received an urgent call.
The first reports the discussion as a past event.
The second presents it as an activity already underway when something else happened.
A long situation can still use the Simple Past tense:
She managed the department for eleven years.
And a brief activity can still be shown as ongoing:
For a few seconds, everyone was staring at the blank screen.
Duration alone does not decide between the two forms.
Stative Verbs and the Past Continuous
Some verbs usually describe states rather than activities. These are often called stative verbs.
Common examples include:
know, believe, understand, want, need, own, belong, prefer, seem
When these verbs express a state, they do not normally appear in continuous forms.
I knew the answer.
Not normally:
I was knowing the answer.
The company owned several properties at the time.
Not normally:
The company was owning several properties at the time.
Some Stative Verbs Can Have Dynamic Meanings
The same verb can sometimes take a continuous form when its meaning changes.
Compare:
I thought the original estimate was too high.
Here, thought means believed.
I was thinking about the revised estimate.
Here, thinking describes an ongoing mental activity.
Or:
She had a large office.
Here, had expresses possession.
She was having lunch with a client.
Here, having describes an activity.
So the meaning of the verb in context matters more than simply memorising a list.
Can We Say Was Being or Were Being?
Yes, especially when be describes temporary behaviour.
The consultant was being unusually cautious during the negotiations.
The children were being remarkably patient during the delay.
Compare:
Marcus was rude.
This describes him or his behaviour in a past situation.
Marcus was being rude.
This focuses on the behaviour as something happening at that particular time.
We do not normally use being for ordinary identity or permanent description.
Not normally:
The building was being tall.
Understanding the Past Continuous
The Past Continuous is most useful when you want to look at a past situation from inside it rather than simply report that it happened.
The auditors were examining the accounts when they discovered the discrepancy.
Several teams were working remotely during the renovation.
Customer demand was increasing throughout the summer.
Reporters were gathering outside while officials were preparing a statement.
The situations are different, but the perspective is the same: something was already happening, developing, or continuing at a particular point or period in the past.
