Could/ couldn’t

Past modals of ability

We use could to talk about things we were able to do in the past.

It’s the past form of can when we talk about ability.

👉 Think of it as “can in the past.”

✅ Examples:

  • When I was 6, I could swim.
  • My grandmother could play the piano beautifully.
  • We could run very fast when we were teenagers.

We use couldn’t to say we were not able to do something in the past.

✅ Examples:

  • I couldn’t ride a bike when I was 5.
  • She couldn’t speak English last year.
  • We couldn’t use computers when we were children (because there were none at home!).

We also use could to ask about abilities in the past.

✅ Examples:

  • Could you swim when you were 7?
  • Could your father drive a car when he was young?
  • Could your grandmother speak another language?

🧾 Useful Tips

✨ Notice the difference:

  • I can swim = now, in the present.
  • I could swim when I was 6 = in the past.

✨ Pronunciation tip:

  • could is pronounced /kʊd/ (like good).
  • The l is silent!

✨ Everyday English:
We sometimes use could in polite offers or suggestions:

  • Could you help me, please?
  • We could go to the park this afternoon.
    👉 But in today’s lesson, we are focusing on past ability.
