When do we use past continuous?

Past continuous describes an action already in progress at a specific point in the past: "I was sleeping when you called." "What were you doing at 8 PM?" The action started before that moment and was still happening at it.

It also sets the scene with background description ("It was raining when I left the house") and shows two actions happening at the same time in the past ("While she was reading, he was cooking").

Past continuous vs past simple

Past continuous is the background, ongoing action; past simple is the shorter event that interrupts it or happens next. "I was sleeping [background] when you called [interrupting event]." "When" often introduces the past-simple interruption, while "while" introduces the past-continuous background.

Storytelling mixes the two: past continuous paints the scene, past simple delivers what happened. Using past continuous for every past action is a common overuse — most single, completed events still need plain past simple.

Common Mistakes

  • ✗❌ "I was sleep when you called" → ✓ "I was sleeping" (need -ing form)
  • ✗❌ "I was knowing the answer" → ✓ "I knew the answer" (stative verbs don't use continuous)
  • ✗❌ "What did you doing at 8?" → ✓ "What were you doing at 8?" (use was/were, not did)

Tips

  • ✓"When" often signals the interrupting event (Past Simple); "while" signals the background action (Past Continuous).
  • ✓Combine with Past Simple for storytelling: background (Past Continuous) vs. key events (Past Simple).

Advanced Notes

Past Continuous is primarily a narrative tool — it sets the scene while Past Simple delivers the plot events. The classic structure is "was/were + -ing WHEN simple past" (interrupted action) or "while was/were + -ing, was/were + -ing" (parallel actions). Learners often overuse it, applying it to all past actions. It's important to note that it rarely appears in isolation in real text; it almost always pairs with Past Simple in the same sentence or surrounding context.

FAQ

What is the difference between past continuous and past simple?

Past continuous (was/were + verb-ing) describes an action already in progress at a specific past time or in the background. Past simple describes a completed event, often the one that interrupts it. "I was sleeping [continuous, background] when you called [simple, interrupting event]."

Why is "I was sleep when you called" wrong?

Past continuous needs the -ing form of the verb after was/were — "sleep" on its own is just the base verb. The correct form is "I was sleeping when you called."

Why can't you say "I was knowing the answer"?

Know is a stative verb (it describes a state, not an ongoing action), so it doesn't take the continuous form even in the past. Say "I knew the answer" instead — the same rule that blocks "I am knowing" in the present also blocks it here.

Is it "What did you doing at 8?" or "What were you doing at 8?"

"What were you doing at 8?" — past continuous questions use was/were, not did. Did only appears with the base verb in past simple questions ("What did you do at 8?"), never together with an -ing verb.

When do you use "when" and when do you use "while" with past continuous?

"When" usually introduces the shorter, interrupting action in past simple: "The phone rang when I was cooking." "While" usually introduces the background action in past continuous: "While I was cooking, the phone rang." Both sentences describe the same event — the choice depends on which clause you're emphasizing.
