Modals of permission: meaning and examples
Modals of permission are modal verbs used to express permission, make a request, or give someone the right or opportunity to do something. Let’s imagine a situation: you’re sitting in an office with your colleagues, the air conditioner isn’t working, and you really want to open the window.
What would you say in English?
- Can I open the window, please? — as an option.
- May I open the window? — the same meaning, but said more politely and formally.
Let’s go over the main modal verbs of permission and the differences between them, so you won’t get confused and can feel confident in what you say.

How to give or deny permission in English
When someone asks you for permission, it’s important not just to say yes, you can or no, you can’t, but to respond politely and naturally. Here’s how to do it:
- Sure, go ahead!
- Yes, of course.
- No problem!
- Feel free.
- That's fine with me.
- Absolutely!
- You may. (formal option)
— Can I borrow your charger?
— Sure, go ahead!
— Would you mind if I opened the window?
— Not at all. Go ahead!
When refusing permission, try to avoid a harsh no — even if you really want to say it. It’s important to stay polite and consider the context. Even a refusal can sound friendly.
- I'm afraid not.
- Sorry, but that's not possible.
- I'd rather you didn't.
- Unfortunately, no.
- That might not be a good idea.
- I’m not comfortable with that.
— Is it okay if I bring a friend to the meeting?
— I’m afraid not, it’s a private session.
— Do you mind if I use your phone?
— I’d rather you didn’t. It’s my work phone.

FAQs
1. What’s the difference between can and may?
The difference lies in the situation and who you’re speaking to. In a friendly setting with colleagues, you can use can, but when talking to someone like your manager or boss, it’s better to use may.
- Can – informal, used among friends or in casual situations.
- May — more formal, used in professional or academic contexts.
2. Can I use Could I… instead of Can I…?
Yes! Could I… sounds softer and more polite. Since it’s technically the past form of the verb, it adds a more hypothetical tone, making the request feel less direct and more formal (like Could I possibly… instead of just Can I…).
3. What should I say after yes if I want to give permission?
Yes, you can is a bit too direct and might sound harsh in some situations. It’s better to use softer and more polite options like:
- Sure, go ahead!
- Of course!
4. Is it correct to say Can I able to…?
No, that’s incorrect. Can and be able to have similar meanings (both express ability), but they cannot be used together in the same phrase. Correct options:
- Can I use your phone?
- Am I able to use your phone?
