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.
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.
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.
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.
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.
