Origin

Old English cunnan 'know' (in Middle English 'know how to'), related to Dutch kunnen and German können; from an Indo-European root shared by Latin gnoscere 'know' and Greek gignōskein 'know'.

Usage

Is there any difference between may and can when used to request or express permission, as in may/can I ask you a few questions? Many people feel that can should be reserved for expressions denoting capability, as in can you swim? , rather than for those relating to permission. May is, generally speaking, a politer and more formal way of asking for something, and is the better choice in more formal contexts.
