The question of whether a period goes inside or outside of quotes is a common debate among writers, editors, and language enthusiasts. While it may seem like a trivial matter, the correct placement of a period in relation to quotes can impact the clarity and coherence of written communication. In this article, we'll delve into the rules and guidelines surrounding this issue, exploring the various scenarios in which a period may be placed inside or outside of quotes.
Historical Context
The use of periods in relation to quotes has a long history, with different styles and conventions emerging over time. In ancient Greece and Rome, for example, periods were often placed inside quotation marks to indicate the end of a direct quote. This convention was also adopted in medieval Europe, where it remained in use until the 18th century.
Modern Conventions
Today, there are two primary styles for placing periods in relation to quotes: the American Psychological Association (APA) style and the Modern Language Association (MLA) style. According to the APA style, a period is placed outside of quotation marks when they are used to set off a quotation that is not a direct quote. In contrast, the MLA style places a period inside quotation marks when they are used to set off a direct quote.

Direct vs. Indirect Quotations
One of the key factors in determining whether a period goes inside or outside of quotes is whether the quotation is direct or indirect. A direct quote is a verbatim repetition of the original text, whereas an indirect quote is a paraphrased or summarized version of the original text. When using direct quotes, the period is typically placed inside the quotation marks, while indirect quotes have the period outside.
- Direct quotes: "The cat is sleeping." (period inside)
- Indirect quotes: According to the author, the cat is sleeping. (period outside)
Special Cases
There are several special cases in which the placement of a period in relation to quotes may vary. For example, when a quotation is interrupted by a punctuation mark, the period is typically placed outside the quotation marks. Additionally, when a quotation is set off by ellipses, the period is placed outside the quotation marks.
| Scenario | Period Placement |
|---|---|
| Interrupted quotation | Period outside |
| Ellipses at the end of a quotation | Period outside |
Style Guides and Conventions
Style guides such as the Chicago Manual of Style and the Associated Press Stylebook offer guidance on the placement of periods in relation to quotes. These guides often recommend a specific style, but may also provide exceptions or special cases. It's essential to consult these guides and adapt them to your writing style and audience.

Consistency and Clarity
In conclusion, while there are various conventions and style guides surrounding the placement of periods in relation to quotes, the key consideration is consistency and clarity. By adopting a consistent style and using clear and concise language, writers can effectively communicate their ideas and engage their audience. Remember, the correct placement of a period may seem trivial, but it can significantly impact the overall quality and impact of written communication.
