A comma can make a big difference! The Oxford comma is one thing that has not made sense to me since I first learned it in middle school. I can understand the reasoning behind it, but it changes the syntax. An Oxford comma (sometimes called a serial comma) is the comma before the coordinating conjunction when listing things. Allow me to give an example: For breakfast this morning, I had eggs, sausage, toast, and orange juice. The serial comma is the on after the word "toast". Since I did not have orange juice on my toast, I add a comma between them. This is compliant with the Chicago Manual of Style. However, it is uncommon to see an Oxford comma in the UK. The reasoning behind this is that each comma represents the word "and", and that, since "and" is already written, then there is not need for a comma. The way that I see it is that not all commas represent "and", so it should not be used as such. What are some of your thoughts on this? Only ESL students please.
