Period Placement with Closing Quotation Marks in APA Style
In APA Style, the period always belongs inside the closing quotation mark when the quoted material is part of a sentence. This rule applies to end punctuation for quoted matter and is consistent across the 7th edition. When the quoted material is a full sentence that ends with its own period, place the original period inside the quotation marks and follow with the sentence period if needed. For parenthetical citations, ensure commas and periods still sit inside the quotation mark before the closing parenthesis.
Core Rule and Examples
APA prioritizes clarity and consistency in punctuation. For periods specifically, the standard guidance is straightforward:
- Place the period inside the closing quotation mark when quoting a sentence that ends with a period.
- Place the period outside the closing quotation mark only when the sentence itself ends with a question mark or exclamation point, and the quote is part of that sentence.
Example: She said, “This is a direct quote.” The period sits inside the quotes because the quoted sentence ends with a period. In contrast: Did she really say, “This is a direct quote”? Here the question mark governs the sentence structure, and the quote’s internal punctuation remains unchanged.
Short Quoted Fragments
When quoting a short phrase that is part of a larger sentence, the period that concludes the overall sentence should appear after the closing quotation mark. However, if the quoted fragment itself contains a period, retain it inside the quotes and then add the sentence-ending period outside if needed for clarity. APA guidance emphasizes preserving the original punctuation of the source while ensuring the sentence you construct reads smoothly.
Practical Application in Citations
In in-text citations, the same principles apply. The period that ends the sentence comes after the closing parenthesis of the citation. However, when you incorporate a direct quotation, the quotation marks surround the exact wording, and the period belongs inside those quotation marks before the citation parenthesis if the quote is a full sentence. Consider this structure:
Author (Year) stated, “Exact wording here.” (p. X).
Note how the period inside the quotes closes the quoted sentence, and the period after the parenthesis closes the overall statement.
Parenthetical Citations and Periods
With parenthetical citations, place the comma or period that ends the sentence inside the closing parenthesis if the quote is part of the sentence. If the quote itself ends with a period, that period stays inside the quotation marks, followed by the sentence period outside if they are distinct. This approach maintains consistency and avoids ambiguity about which punctuation belongs to the quote and which belongs to the surrounding text.
Common Misconceptions and Troubleshooting
Some writers mistakenly believe the period should always go outside quotation marks, a style common in British English or certain disciplines. In APA 7th edition, however, American English conventions prevail, and the period remains inside the closing quotation mark. Another confusion arises when block quotes are used. For block quotations (40 words or more), the quotation block is indented, and the period precedes the in-text citation, placed before the closing parenthesis, not before the closing quotation mark if the block quote ends with its own punctuation.
Block Quotations and Period Placement
When dealing with block quotations, the rules shift slightly. Introduce the block quote with a signal phrase and a colon. The period that concludes the block quote appears before the citation and closing punctuation. For example:
Smith (2020) argued that clarity is essential: “Every sentence should be crafted with care. The reader depends on punctuation to disambiguate meaning” (p. 45).
In this instance, the first sentence of the block quote ends with a period inside the quotation marks, and the citation follows. The overall statement then concludes with a period after the citation if necessary. This method keeps the attribution clear and the punctuation logically ordered.
Reference List and Periods in Titles
In the reference list, periods also appear inside the closing quotation marks when a title or work being referenced includes quoted matter. For example, a book title that itself contains a quoted phrase should retain the internal punctuation as it appears in the original. APA emphasizes accurately reproducing the source’s title formatting, including quotation marks and internal punctuation, to ensure proper attribution and traceability.
Quick Reference: Period Placement Cheat Sheet
| Context | Period Placement | Example |
|---|---|---|
| Quoted sentence ending with a period | Inside the closing quotation mark | She said, “This is correct.” |
| Sentence ending with question mark or exclamation point | Outside the closing quotation mark | Did he say, “We should leave”? |
| Block quotation concluding a sentence | Before the citation, inside the quotation if the quote ends with a period | …as noted earlier: “Data supports this trend” (Jones, 2019, p. 12). |
| Short quoted phrase within a sentence | Sentence period after the closing quotation mark | She used the term “coding” in her analysis. |
Why This Matters for Academic Writing
Consistent punctuation in quotes supports readability and reduces ambiguity. In APA, the period inside the closing quotation mark signals that the quoted material is a complete syntactic unit. This convention helps readers distinguish between the author’s writing and the sourced material. Following these rules also aligns your work with peer-reviewed expectations, journal guidelines, and institutional standards, minimizing revisions during the publication process.
Final Guidance and Best Practices
When in doubt, consult the official Publication Manual of the American Psychological Association or a reputable APA style resource. Prioritize accuracy over speed when preparing manuscripts, especially when quotations are frequent. Use search-and-check routines in your writing tool to verify punctuation placement, and consider creating a style checklist that includes quotation marks, parentheses, and block quote formatting. Applying these principles consistently enhances professionalism and credibility in scholarly communication.
