Past Simple vs Past Continuous
Both are past tenses, but they see the action differently. Use:
- Past simple for a completed action — I cooked dinner.
- Past continuous for an action in progress — I was cooking dinner.
- Together: continuous sets the scene, simple is the event — I was cooking when he arrived.
Longer or background action → past continuous; shorter, completed action or interruption → past simple.
The difference at a glance
| Past Simple | Past Continuous | |
|---|---|---|
| Action | completed | in progress |
| Length | the whole action or a short event | a longer, background action |
| In a story | the events | the scene / setting |
| Example | The phone rang. | I was sleeping. |
The key question: completed, or in progress? A finished action takes the past simple; an action already happening at that moment takes the past continuous.
Use the past simple for…
- a completed action: I finished work at six.
- a sequence of events: She arrived, sat down and ordered.
⚠️ Typical error:
She was arriving, sitting down and ordering.→ For completed actions in sequence, use the past simple: She arrived, sat down and ordered.
Use the past continuous for…
- the scene or background: The sun was shining and the birds were singing.
- a longer action interrupted by another: I was walking home when it started to rain.
⚠️ Typical error:
I walked home when it started to rain(if the walking was already happening) → I was walking home when it started to rain.
Common mistakes
1. Past simple for the background action. The longer, interrupted action takes the past continuous. I read when the lights went out → I was reading when the lights went out.
2. Past continuous for a short, completed action. The phone was ringing and I was answering it quickly → The phone was ringing and I answered it quickly. Pro tip: the quick reaction is the past simple.
3. Past continuous with stative verbs. I was wanting to leave → I wanted to leave.

Frequently asked questions
How do the two tenses work together?
The past continuous sets a longer background action; the past simple is the shorter action that interrupts it: I was reading (background) when the phone rang (event).
When do I use 'when' and 'while'?
Use 'while' + past continuous for the longer action (while I was reading), and 'when' + past simple for the shorter one (when the phone rang).
Does 'I was cooking when he arrived' mean the same as 'I cooked when he arrived'?
No. 'I was cooking when he arrived' means the cooking was already in progress. 'I cooked when he arrived' means I started cooking after he arrived — a sequence.
Which tense is used for storytelling?
Both: the past continuous sets the scene (It was raining), and the past simple carries the events (She opened the door).
