Punctuation: The Oxford Comma
I'm horrible with punctuation so it should be no surprise I didn't know what an Oxford comma was. I had wondered, though, when I'd read news and other writings where a comma was placed where I didn't think one was needed such as "My heart beats true for the red, white, and blue". They were often written by educated and experienced writers.
I was under the impression that last comma shouldn't be used when "and" is present, but that's an Oxford comma. It's use is debatable. Bumped into this online explanation of Oxford commas yesterday. Up until now I just thought its use was wrong, but did wonder about it sometimes as it seemed to match the way we talk.
I see one of the reasons they list for using it is just that: "Matches the natural speech pattern of pausing before the last item in a series.". I'll try and use it that way when applicable from now on. I don't think the example of theirs that I used in the first paragraph needs the last comma. Doesn't match natural speech.
