Understanding the Period Before or After Parentheses
The use of periods (.) before or after parentheses can be a source of confusion, particularly in formal writing and grammar. While it may seem like a minor detail, the placement of the period can significantly impact the clarity and meaning of a sentence. In this article, we will explore the rules and best practices surrounding the use of periods before or after parentheses, as well as provide examples to illustrate these concepts.
General Rule: Periods After Parentheses
According to the standard rules of punctuation, a period should be placed inside the parentheses if the parenthetical remark is a separate sentence. For example:
- Sarah graduated from college (summa cum laude) in 2018.
However, if the parenthetical remark is not a complete sentence, the period should be placed after the parentheses. For instance:

- Sarah graduated from college, (summa cum laude) a feat that required dedication and perseverance.
Special Case: Ellipses and Dashes
When using an ellipsis (...) or a dash (-) before or after parentheses, the rules can be slightly different. For example:
- The author's life was marked by numerous challenges... (including the loss of her parents at a young age).
- She was a brilliant writer—(one of the best in her generation).
As you can see, in both cases, the period is placed after the parentheses. This is because the ellipsis and dash are used to indicate a pause or a break in thought, rather than to separate a complete sentence from the rest of the text.
Quotations and Parentheses
When using parentheses within a quotation, the rules can become even more complex. In general, if the quotation is a complete sentence, the period should be placed after the quotation marks and the parentheses. For example:

- 'I graduated from college,' she said, (proudly displaying her diploma).
However, if the quotation is not a complete sentence, the period should be placed inside the parentheses. For instance:
- 'I'm glad I graduated from college'... (she said with a smile).
Tabular Summary
| Scenario | Placement of Period |
|---|---|
| Parenthetical remark is a complete sentence | Period inside the parentheses |
| Parenthetical remark is not a complete sentence | Period after the parentheses |
| Ellipsis or dash before or after parentheses | Period after the parentheses |
| Quotation with parentheses | Period after the quotation marks and parentheses (if quotation is a complete sentence) |
Conclusion: Clear and Consistent Writing
The use of periods before or after parentheses is an important aspect of clear and consistent writing. By following the rules outlined in this article, you can ensure that your writing is grammatically correct and easy to understand. Remember, the key is to consider the context and purpose of the parenthetical remark, as well as the type of punctuation used. With practice and attention to detail, you can master the nuances of punctuation and become a more effective writer.
