Comma Inside Or Outside Quotes

The question of whether to place a comma inside or outside quotes is a common dilemma in writing, particularly when dealing with dialogue, quotations, or titles. The rule for comma placement in relation to quotation marks can vary depending on the style guide being followed, such as the Chicago Manual of Style (CMS), the Associated Press Stylebook (AP), or the Modern Language Association (MLA) style.
Chicago Manual of Style (CMS)

According to the Chicago Manual of Style, commas and periods are placed inside quotation marks, regardless of whether the quoted material is a complete sentence or a fragment. This style is commonly used in book publishing and academic writing. For example: “I love reading books,” she said. The comma after “books” is placed inside the quotation mark because it is part of the dialogue’s punctuation.
AP Style
The Associated Press Stylebook, on the other hand, suggests placing commas and periods outside quotation marks when they are not part of the quoted material. However, AP style typically uses quotation marks for quotations that are not set off from the rest of the text, and in such cases, commas and periods are usually placed inside the quotation marks for clarity. An example following AP style might look like this: She said, “I love reading books,” and then she walked away. Here, the comma after “books” is part of the sentence structure rather than the quotation itself.
Modern Language Association (MLA) Style

The MLA style, often used in humanities, places commas and periods inside quotation marks, similar to the CMS. This style emphasizes the importance of the quoted material’s integrity, suggesting that punctuation should be treated as part of the quotation. For instance: The teacher asked the student, “What is your favorite book?” In this case, the question mark is part of the quotation and thus placed inside the quotation marks.
