both have the same meaning today but 'may' is more polite than 'can'.

may = permission can = ability or permission "can" often replaces "may". "may" is getting outdated.

Can = "to be able to." May = "to be permitted to." Incorrect: Can we talk? (Well, if you can say it, you are able to talk!) Correct: May we talk? Correct: We may talk if you can listen to my side ................... 1- "can": to indicate capability or possibility e.g. "I don't know if I can lift this piano by myself." explain :Here we are asking if you have the physical capacity or mental acuity to get the piano lifted. 2- "May": is used when you are asking permission e.g "May I lift your piano for a little exercise?" explain :Here you wish the permission of someone to carry out an action.

Elliot and KentPaul are both correct. 'May' is used for permission but 'can' is used for both ability and permission. May is very formal/polite and is not used so often. It is always used in some situations, though. E.g., If you use gesture rather than saying the full sentence: 'May I ...?', when gesturing towards a free chair that that you want to take from someone's table in a pub.
