Strictly speaking 'may' means you have permission and 'can' means that
it is something you are physically/mentally able to do.
Child: Can I go to the toilet please?
Teacher (correcting the child): You may.
Providing the child is mobile and has a working sphincter then /of
course/ she can go to the toilet. Whether or not she has the teacher's
permission to leave the classroom is another matter.
However, I'm afraid it's a losing battle and so 'can' is increasingly
being used where 'may' would be more appropriate. My guess is that 'you
can be sure' references are more prevalent post 1950 than before.
You may be sure = you have my permission to expect this of me (=I promise)
You can be sure = ?? you have the mental faculties to decide this for
yourself?
Similarly,
Wife: Can you make me a cup of tea?
Me: I course I can, the question is 'Will I?' <ducks thrown book>

Yes.

I fully agree, and this is one of the reasons I've posted this, to
sample the opinions of others on this change.

This is how I am reading them, including the ??:-)
Thanks.

I agree with the foregoing.

I disagree. "You may be sure" should mean[1] that the person has
permission to be sure, which is nonsense except in a thought-police state.
"You can be sure that foo", otoh, should mean[1] that the person has the
ability to be sure that foo -- because foo is, one assures him, true.
Nonetheless, "you may be sure" has certainly been more common, and, I
think, still is.
[1] Whatever "should mean" means.

"Can", of course, signifies actual ability. "May", in these sorts of
constructions, signifies (I quote my trusty desk dictionary)
"contingency, as in clauses of purpose, result, concession, or
condition [they died that we may be free]." So in a practical sense,
the two are identical, each promising assurance of the point in
question. It's really a matter of euphony or style--that is,
taste--which to use.
(That is AmEn; if there is a difference in BrEn, I would be surprised
to haer of it.)
