Past Continuous Tense

The past continuous is the English verb form made with was or were plus the -ing form of a verb, used for an action that was in progress at a particular time in the past. It most often supplies the background against which a shorter past simple event happens.

An aspect built on a tense

The past continuous is usually taught as the second past tense a learner meets, and in a classroom that is a sensible fiction. Strictly, it is not a tense at all.

The Cambridge English TKT Glossary, the reference list used across the Teaching Knowledge Test, defines aspect as a way of looking at verb forms without looking specifically at the time of the action or event, and adds that the continuous/progressive aspect may describe an action that is in progress at a particular time. English marks tense in two places, present and past, and the past continuous is the past tense of be with continuous aspect stacked on top. The time comes from was and were. The sense of being in progress comes from -ing.

That matters in practice for one reason. Everything a class already knows about was and were, including the negative, the question and the fact that did never appears, transfers directly to the new form. A teacher who presents it as a fresh tense with fresh rules is making it harder than it is.

How it is formed

The British Council states the rule in one line: the past continuous is made from the past tense of the verb be and the -ing form of a verb. Because the auxiliary is be, the negative and the question are simpler than in the past simple. There is no did to introduce and no base form to return to.

Form	Pattern	Example
Affirmative	subject + was or were + verb + ing	She was reading. They were talking.
Negative	subject + was not or were not + verb + ing	She was not reading. They were not talking.
Question	was or were + subject + verb + ing	Was she reading? Were they talking?
Short answer	yes or no + subject + was or were	Yes, she was. No, they were not.
Contracted	wasn’t, weren’t	She wasn’t reading. Weren’t they talking?

The spelling of the -ing form follows the same three rules as the present continuous: a final silent e is dropped, as in making; a single final consonant after a single stressed vowel is doubled, as in sitting and running; and ie becomes y, as in lying. A class that has done the present continuous has already done this.

The five uses, in the British Council wording

The British Council LearnEnglish grammar reference lists five uses. The first is the one every coursebook teaches and the one most worth the lesson time. The other four are extensions of the same idea, that the action was spread out over a period rather than done at a point.

Use	Example
Something which happened before and after another action	The children were doing their homework when I got home.
Something that happened before and after a specific time	It was eight o’clock. I was writing a letter.
To show that something continued for some time	My head was aching. Everyone was shouting.
Something that happened again and again	I was practising every day, three times a day. They were always quarrelling.
With verbs which show change or growth	The children were growing up quickly. Her English was improving.

Use categories and examples quoted from the British Council LearnEnglish page Past continuous. The fourth use, with always, usually carries a note of irritation, and that is worth teaching because learners who use it neutrally will sound more annoyed than they mean to.

The interrupted action pattern

This is the pattern the form is taught for and the pattern most of its real use falls into. Two past actions are set against each other. The longer one, already in progress, takes the past continuous. The shorter one, which happens in the middle of it, takes the past simple.

The two sentences describe the same event. What changes is which clause carries when or while, and the choice is not free.

Word	Goes with	Pattern	Example
when	the past simple, the short event	past continuous + when + past simple	I was cooking when the phone rang.
while	the past continuous, the long action	past simple + while + past continuous	The phone rang while I was cooking.
as	the past continuous, like while	past simple + as + past continuous	The phone rang as I was cooking.

The clauses can be swapped round in every row with a comma, so When the phone rang, I was cooking is equally correct. What does not work is while with the short event. While the phone rang makes the ring last as long as the cooking, which is rarely what the speaker means.

Two further points belong in the same lesson. First, two past continuous forms together mean two long actions running in parallel: I was cooking while she was reading, with no interruption at all. Second, two past simple forms together mean one event followed by another: When the phone rang, I answered it. Only the mixed pattern gives the interruption, and that is why the form is taught in contrast with the past simple rather than on its own.

How it is used in practice

1. Draw the timeline before you say the rule. A long wavy line for the continuous action and a short vertical stroke cutting across it for the past simple event. The picture does more than the explanation, and learners can point at it when they are not sure which form a clause needs.
2. Teach it against the past simple, not after it. The form has no meaning on its own in the interrupted action pattern. Every presentation sentence should contain both forms, and every controlled practice item should make the learner choose between them.
3. Ask what the context trains. A lesson built on what were you doing at nine o’clock last night trains the continuous for every verb last night, which is the failure case below. A context built on interruptions trains the contrast.
4. Use a concept checking question on duration. Did the walking take a long time? Did the rain start suddenly? Which started first? Three questions settle most cases faster than a rule does.
5. Keep stative verbs out of the practice stage. A gap fill that asks learners to put know or want into the past continuous teaches an error. Choose activity verbs for the practice and deal with the stative limit as a separate, short stage.

A worked classroom example

An A2 group of ten adults in a morning class, mostly Spanish and Brazilian Portuguese speakers with one Polish and one Vietnamese learner. The target is the past continuous in the interrupted action pattern, and the teacher has sixty minutes.

She opens with a short story about her own weekend. She was cycling to the shops when her chain came off. She was fixing it when a neighbour stopped to help. The class listens twice and on the second listening writes every verb they hear, which gives a board list of was cycling, came off, was fixing, stopped. She asks the class to sort the four into two columns and to say what the difference is, which is guided discovery and takes a few minutes.

She draws the timeline, labels the two columns with it, and the class produces the pattern correctly in the controlled stage. Then the freer practice, in which learners tell a partner about something that happened to them last week, produces this from one of the Spanish speakers: I was watching a film when my brother was arriving.

The teacher does exactly that, on the board, with the class watching. She draws the long line for watching a film, asks where the arriving goes, and the learner draws a short stroke across it without being told. The next three sentences from the group all carry the contrast. The repair cost two minutes and it was cheaper than a second lesson.

Common learner errors

The form is easy. Almost every error is in the choice between the two past forms, and the pattern of errors is predictable from the learner’s first language, which makes this one of the clearer cases of L1 interference in the tense system.

Error	Example	Where it comes from	What to do
Both clauses continuous	I was watching TV when he was arriving.	A presentation context that trains past story equals continuous. Not L1 driven; it appears in every first language group.	Return to the timeline and ask which action was short. Let the learner supply the past simple.
Continuous with a stative verb	I was knowing him for years. She was wanting a coffee.	Overextension of -ing to states. Qian (2015) found both Chinese and Mongolian learners doing this and read it as L1 transfer, and it is frequent in Slavic groups, where the imperfective covers states as well as actions.	Teach a short list of stative verbs as vocabulary. Practise the past simple of know, want and need directly.
Continuous for a past habit	When I was a child I was going to school by bus every day.	Spanish, Portuguese, Italian and French have an imperfect tense that covers habit, state and action in progress in one form. Learners map the whole imperfect onto the continuous.	Give used to and the past simple for habits, and keep the continuous for a single occasion in progress.
Underuse: the simple for an action in progress	I read a book when he came in.	German and Dutch have no grammatical progressive. Roberts and Liszka (2021) found German and Dutch learners of English processing progressive and simple sentences the same way even when they knew the rule.	Make the contrast audible: drill minimal pairs where only the form changes the picture, and insist on the timeline.
Missing auxiliary	I going home when I saw her.	The auxiliary carries no meaning the learner can hear, so it is dropped under pressure. Common in Vietnamese, Thai and Mandarin groups and in early learners of every background.	Drill the contracted negative and the question, both of which make was and were impossible to drop.
While with the short event	While the phone rang, I was cooking.	Learners treat when and while as synonyms, which they nearly are in many first languages.	Teach while as belonging to the continuous clause only, and give when as the safe default.

What the research says about how it is learned

The best developed account of how second language learners pick up English tense and aspect is the Aspect Hypothesis, set out at book length by Bardovi-Harlig (2000). Its claim about the progressive is specific: learners first attach -ing to activity verbs, the ones that describe something going on with no built in endpoint, such as walk, play and talk, and only later extend it to verbs with an endpoint and, in error, to states.

Muñoz and Gilabert (2011) tested this with instructed Catalan and Spanish bilingual learners of English and found the association between -ing and durative verbs held across proficiency levels, though not as tightly to activity verbs as the strongest version of the hypothesis predicts. Qian (2015) found the same prototype pattern in Chinese and Mongolian learners and, alongside it, the overextension of -ing to stative verbs noted in the error table above.

Two limits are worth stating. Most of this research describes what learners produce, not what instruction should do about it, and Thane (2018) reviews a body of later work showing that first language, task type and the teaching materials all bend the sequence. For a classroom the practical reading is modest: start the form on activity verbs, because that is where learners will place it anyway, and treat the stative limit as a separate teaching point rather than expecting it to emerge.

Frequently asked questions

What is the past continuous tense?

It is the English verb form made with was or were plus the -ing form of a verb, as in I was working and they were waiting. It describes an action that was in progress at a particular time in the past, and it most often sets the scene for a shorter event told in the past simple.

Is the past continuous the same as the past progressive?

Yes. The two names describe one form. British coursebooks and the Cambridge teaching awards tend to say continuous, while North American materials and much of the research literature say progressive. Learners will meet both labels and should be told they mean the same thing.

How do you form the past continuous?

Use was with I, he, she and it, and were with you, we and they, followed by the verb plus -ing. The negative puts not after was or were, and the question moves was or were in front of the subject. No did is involved at any point, which is the main formal difference from the past simple.

What is the difference between the past continuous and the past simple?

The past simple reports a completed event and moves a story forward. The past continuous describes an action that was already in progress and gives the background. In I was cooking when the phone rang, the cooking was under way, the ring interrupted it, and the two forms together tell the listener which was the longer action.

Which verbs are not used in the past continuous?

Stative verbs, which describe states rather than actions, are not normally used in any continuous form. These include know, believe, want, need, own and belong. The British Council gives the example that on getting home a speaker needed a shower rather than was needing one. A few verbs, such as think and have, are stative in one meaning and dynamic in another.

When is the past continuous taught?

Most coursebooks introduce it at A2, usually a few units after the past simple and almost always in the interrupted action pattern with when and while. It is then recycled at B1 for narrative writing. The practical trigger is that learners can already form the past simple and know was and were, because the new form depends on both.
