1. Past ability or possibility

One common use of could is to talk about your ability to do something in the past. We use can when the possibility or ability we are referring to is in the present.

Present: I can convince him easily.
Past: I could convince him, but the management did not let me talk to him.

Present: We can’t sleep with these kids being here. They annoy me.
Past: We could not sleep there. The kids were annoying us.

Present: I can help you if you want.
Past: I could help you finish the assignment on time. Why did you not call me?

Present: Jon can speak 4 languages.
Past: I could speak Chinese a little when I was in school.

NOTE: We use can when we refer to someone’s ability or the possibility of an event in the present but it is grammatically fine to use could either.

  • I could easily beat you in chess. I am a gold medalist in it.
  • I am not sure If you could eat this all in 10 minutes. I am not that hungry either.

2. Polite requests

Another common use of could is to make polite requests to others.


  • Could you move a little to your left?
  • Could you take a photo of us?
  • Could you help me with this?

NOTE: Using the word ‘please’ makes the request even more polite. Use it to come across as a polite and humble person.

  • Could you please pass that water bottle?
  • Could the management please let me take charge of this project?
  • Could you please get me something to eat?
  • Could you all please make the payment tonight?

It is important to note that the modal verbs could, would, and even can are also used to make requests.

  • Could you show me the way to the washroom?
  • Can you show me the way to the washroom?
  • Would you show me the way to the washroom?
  • Would/Do you mind showing me the way to the washroom?

Could, amongst all the other modal verbs, is considered more polite and formal though.

3. Asking for permission

We generally use could when asking for permission from people. There is a significant difference between making a request and asking for permission. The latter seeks a nod from an authoritative person, and the former usually looks for outside help.

Both the modal verbs could and may are commonly used to ask for permission. We, informally, use the modal verb can too here.


  • Could I use your laptop for a day?
  • Could I stay here for a night?
  • Could Annie and I go on a date tonight?
  • Could we park our car in your parking lot for some days?

4. To refer to the possibility of an event

Could is also used to refer to the possibility of a situation in the present, past, or future. Let’s study some examples to understand.


  • It could rain today. The sky looks dark.
  • We could lose this match if we don’t play well.
  • This project has a lot of potential in it; it could make us a millionaire.


  • I could die there. Why did you leave me alone with those goons?
  • We could have gotten the contract if we had hired professionals to represent us.


  • They could ask you to give up your post in the meeting tomorrow. Don’t do it at any cost.
  • She could get a call from the university next week.
  • I could be offered a full-time job in the organization very soon.

NOTE: we can also use may, might, or can to refer to the possibility of an event/situation. May indicates a positive possibility, and might indicates a little less positive possibility, while can is considered informal by grammarians to use for talking about the possibility of a situation.


  • You could get selected for this post.
  • You may get selected for this post. (likely to happen)
  • You might get selected for this post. (less likely to happen)
  • You can get selected for this post. (just stating that it is possible)

5. To give suggestions

We often use could to give suggestions. It is considered very polite and formal.
