Thread: Tell me about quotation marks

As far as I've seen, all punctuation is supposed to be inside the quotes. I don't know if this changes for other countries, (I'm in North America) but I've been told by english teachers here: "Always put your punctuation inside your quotes," even if it's not part of what you're quoting.

As for single and double quotations, single quotation marks are only, typically, used inside quotations that cite other quotations; a quote within a quote. In a programmer's world, single quotations are used to identify individual letters. However, is it incorrect to say my name is spelled with an 'I?' Is that what it would say in the "Book Of English Grammar?" In the words of a friend of mine: "English is the craziest language. Even english teachers will probably sometimes say: 'I'm not sure.'"

Note: Everything above is correct according to North American grammar standards (or at least what I know of them). Clever aren't I?

EDIT: If this kind of information is required for an essay or other similar purpose, I'd recommend asking your instructor. It may seem silly, but they're the one who will grade it. So it's their opinion that matters.
