Thanks to Chris 2.0 for the idea (100% not my own). Anyway, he had the idea to start a thread to ask any questions about grammar which we might have, because it's confusing stuff.

My first question is, can someone please clarify the use of inverted commas ('blah') vs quotation marks ("blah")? I understand that directly quoted conversations use quotation marks, but what if you're just quoting a single word or something?
