Certain sets of words in the English language tend to confuse writers. I have found the following to be among them:
MAY / CAN
Have you ever played the game May I? In this children’s game, one person plays the parent and the other children line up beside each other at a starting line some distance in front of the “parent.” The parent then addresses each of the “children” in turn and tells him to take “one giant step” or “three baby steps” or some other method of moving forward. Before doing so, the child is supposed to ask, “May I?” If the child remembers to thus ask permission, then the parent must say, “Yes, you may,” and let that child move forward. If, however, the child forgets to ask permission and merely steps forward as instructed, he is sent back to the starting line. The first child to reach the game’s parent wins.
The point of this demonstration, of course, is to remind us that when asking permission, one should use the verb may, not the verb can (or else the game, no doubt, would be called Can I?).
Incorrect: Dad, can I drive your car tonight? I want to take Shelly to the movies.
Correct: Dad, may I drive your car tonight? I want to take Shelly to the movies.
The verb can means be able to. We assume that the young man asking his dad for permission to drive the car is able to drive (and legally at that) or he wouldn’t be asking permission because he’d know it wouldn’t be granted. Therefore, what we need in this sentence is a verb indicating permission, not ability.
I can drive my father’s car, but I may not be allowed to do so.
Of course, the verb may does have other meanings besides that of permission, and one of those meanings is that of possibility:
I may go to the ballgame tonight or I may not, depending on whether it is raining.
The implication here is not that the speaker has permission to go to the game but that there is the possibility that he will go.
