The Oxford comma – also known as the serial comma – is that little period with a tail that is sometimes used before the coordinating conjuntion in a list of three or more items. Example: I ate ice cream for dinner on Monday, Wednesday, and Thursday. The Oxford comma is the one preceding the word “and.”
Whether or not the Oxford comma is necessary is a topic of hot debate among linguists and grammarians (you know, the cool crowd!). Where you side probably depends on a variety of factors: what you were taught in school, what kind of writer you are, which side of the Atlantic you live on, etc.
I personally am an Oxford comma devotee, so I just loved this!
Where do you fall?
