Footnote Before or After Period Chicago Style
In Chicago style, the rule for footnote before or after period is clear and strict. The footnote number always comes after the period, not before it. Chicago treats footnotes as references, not as part of the sentence itself. That is why punctuation finishes the sentence first, and the footnote marker follows.
Correct Chicago style example:
The study was published in 2022.^1
Incorrect example:
The study was published in 2022^1.
This rule applies to periods, commas, quotation marks, and question marks. Even when a sentence ends with a quote, the footnote number goes after the closing punctuation. Chicago style is widely used in history, literature, and publishing, so following this rule helps your writing look polished, academic, and professional.

This rule keeps writing clear and readable. The footnote acts as a reference, not part of the sentence itself. That is why it comes after the period, not before it.
Different citation styles grew from this tradition, but most kept the same basic placement rule.
