Do Periods Go Inside Or Outside Parentheses

Understanding the Placement of Periods with Parentheses

The question of whether periods go inside or outside parentheses is a common point of confusion in punctuation. The answer depends on the context and the style guide being followed. In general, the placement of a period in relation to parentheses is determined by the information enclosed within the parentheses and its relationship to the surrounding sentence.
Basic Rules
In American English, as per the Chicago Manual of Style, the period is typically placed outside the closing parenthesis if the parenthetical remark is part of a larger sentence. For example: “I went to the store (to buy some milk).”
However, if the parenthetical remark is a complete sentence, the period goes inside the parentheses: “I went to the store (I had to buy some milk).”
British English and Other Styles
In British English, following the Oxford Style Guide, the preference is often to place the period outside the parentheses, regardless of whether the parenthetical remark is a complete sentence or not. But, consistency within a document or publication is key.
Other style guides, such as the AP Stylebook used by journalists, may have their own rules, but the overarching principle is to maintain consistency throughout the writing.
Style Guide | Rule for Period Placement |
---|---|
Chicago Manual of Style | Outside for incomplete sentences, inside for complete sentences within parentheses |
Oxford Style Guide | Generally outside, but check for specific guidance on complete sentences within parentheses |
AP Stylebook | Specific rules may apply, but consistency is key |

Practical Applications

In practical terms, the placement of periods in relation to parentheses can significantly affect the clarity of the text. Incorrect placement can lead to confusion about whether a sentence is complete or if the parenthetical remark is part of the main sentence.
For instance, in academic writing, where clarity and precision are paramount, following the appropriate style guide’s rules on parentheses and periods can make a substantial difference in the overall quality of the writing.
