What this grammar point covers

Modal verbs for permission are special verbs we use in English to ask for, give, or refuse permission. The most common are can, could, and may.

When to use it

Use these forms to ask if something is allowed, to let someone do something, or to say something is not allowed.

Key forms

  • Can I...?
  • Could I...?
  • May I...?
  • You can...
  • You may not...

Examples

Can I use your phone?

May I leave the room?

You can go now.

You may not enter this area.

Could I open the window?

Tips

  • Use 'can' and 'could' for informal situations. 'May' is more formal.
  • Do not use 'will' or 'shall' to ask for permission.
  • Remember: 'Can I' and 'May I' are both correct, but 'May I' is more polite.

Exceptions and edge cases

  • In very formal English, only 'may' is used for permission.
  • In spoken English, 'can' is most common, even in polite requests.
