@Oylok,
Quote:JTT, I don't think tanguatlay really cares which word makes more rational sense in this context.
The OP is probably more interested in knowing which word sound classier.
So ... I think we're looking for the snobbier word, and, clearly, that word is "may."
I don't think you read Ms Tan's question, Oylok. You couldn't have because actually, she asked,
Which word in bold can I use? Or is either acceptable.
That little word 'can', above, underlined; in this sentence it holds the meaning of
permissible.
The answer to that is not to give the one that's most polite and to suggest that because it's more polite, it's somehow more correct. You should have thought this through before you leapt in.
Because not only are both acceptable, again if you had read the pertinent portions of the thread, you might have discovered that English native speakers overwhelmingly choose 'can' over 'may' for permission.
They also choose 'could' over 'may' by a wide margin and I believe 'would be able to ...' over 'may', again by a considerable margin.
Does 'could' in those usages mean "I had the ability"?
Quote:The fact that "can" has so many modern usages just makes the case for "may" that much more compelling. Speak precisely; disambiguate; use "may."
You really don't have any idea how many times that piece of nonsense has been used over the centuries.
Following your line of reasoning, we shouldn't use 'may' because it also has many other modal meanings and these aren't "modern", in the sense of new, usages.
