Permission – Can, Could, May
When we ask for permission to do something we use can, could, may. May is the most formal.
Can I go to the party?
Could I ask a question?
May I sit here?
If we want to be more polite we can use the following construction:
|Do you mind if I||base form of verb|
|Do you mind if I||open the window?|
|Do you mind if I||sit here?|
|Do you mind if I||ask you a question?|
