The Oxford Comma

The Oxford comma, also known as the serial comma, is the final comma used before the conjunction (such as "and" or "or") in a list of three or more items. For example, in the list "apples, oranges, and bananas," the Oxford comma appears after "oranges." Its purpose is to clarify meaning and prevent ambiguity. While some style guides endorse its consistent use, others omit it in certain contexts. Overall, the Oxford comma enhances clarity and precision in written communication by clearly separating items in a list.
