Quoted By:
In English language punctuation, a serial comma, or series comma (also called an Oxford comma or Harvard comma), is a comma placed immediately after the penultimate term (i.e. before the coordinating conjunction [usually and or or]) in a series of three or more terms. For example, a list of three countries might be punctuated either as "France, Italy and Spain" (without the serial comma) or "France, Italy, and Spain" (with the serial comma).
