If your source has two authors, it’s a simple tag team. In your sentence, you just write both last names, connected by the word “and.” For example: Smith and Johnson argue that coffee is the secret to world peace.
Or, if you’re putting the citation in parentheses at the end, it looks like this: (Smith and Johnson 42). See? It’s like Peanut Butter and Jelly—they’re better together, and MLA keeps them linked nicely.
The cool part? You don’t use an ampersand (&) like in APA. Nope, MLA is old-school polite; it loves the full word “and.” It’s like saying “thanks” instead of “thx.”
