A new Grammar Guide quiz is up. Here is the disclaimer for all you sticklers: No, it's not really about grammar; it's about usage and word choice. The sentences all come from real life this time -- from copy I have read or have edited. Of course, we copy editors don't catch everything -- as readers remind us often. We try, though, even in these trying times.

Click here or on the question mark icon to begin the 10-sentence quiz. Be sure to click through to read the explanations (which, by the way, are the same whether you answered correctly or incorrectly). Leave a comment here if you would like or send me a message.

I am on Twitter, too -- #grammarguide.
