In English language punctuation, a serial comma or series comma (also called an Oxford comma or a Harvard comma) is a comma placed immediately 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 '' (with the serial comma), or as "France, Italy and Spain '' (without the serial comma).
