When Writing Styles Collide

Did you know that there are multiple writing styles? Students visiting the Writing Center are usually familiar with MLA style, having learned it in their high school English classes, but different fields and majors may require different writing styles like APA, AP, or Chicago. Different writing styles have different ways of quoting passages, citing sources, placing commas, and even spelling words!

In the tweet above, Brooke Pryor, a journalist from Kansas City, illustrates what happens when writing styles collide. The tweet includes a text screenshot of Brooke and her fiancé debating whether to use Oxford commas on their wedding website. (An Oxford comma is the comma used before the last item of a list of three or more items, before an “and” or “or”. For example: an Italian painter, sculptor, and architect.) As an English major, Brooke’s fiancé wants to use Oxford commas. As a journalist, Brooke wants to leave out Oxford commas.

So who is right?

Technically both. In MLA style (used in English and other liberal arts and humanities fields) it is correct to use Oxford commas, in AP style (used in journalism, mass communications, and public relations) it is correct to leave out Oxford commas. Both Brooke and her fiancé are correctly using Oxford commas based on their respective fields. Since a wedding website is more personal and not a professional or academic piece of writing, the pair could use either writing style, however they cannot use both. Mixing writing styles can confuse readers. Whatever writing style you choose to use, consistency is key!
