puncturation

Puncturation, more commonly referred to as punctuation, is the system of symbols used in writing to separate, organize, and clarify text. It includes marks such as the period, comma, colon, semicolon, question mark, and exclamation point, as well as quotation marks, parentheses, brackets, dashes, hyphens, ellipses, and various diacritical or orthographic signs. These marks help readers parse sentences, indicate pauses and intonation, and distinguish elements such as direct speech, titles, or citations.

The primary purposes of puncturation are to mark sentence boundaries, separate words and phrases, indicate pauses or rhythm, connect related clauses, and signal special functions like quotations or emphasis. Hyphens link compound terms, while dashes set off aside information; commas often clarify or reduce ambiguity; quotation marks denote spoken text or cited material. The rules governing these marks vary by language and style guide, and authors often make stylistic choices within those norms, such as the use or avoidance of the Oxford comma.

Historically, puncturation developed from scribal notes and early punctuation marks used in ancient and medieval manuscripts. Over centuries, printers and typographers standardized many conventions, and modern guidelines—such as the Chicago Manual of Style, APA, and MLA—provide detailed rules for usage across genres. Variation remains across languages; for example, French and many other languages place spaces before certain punctuation marks, while English generally does not.

In digital and multilingual contexts, puncturation must be encoded consistently (for example in Unicode) and applied with attention to readability, accessibility, and the prevailing style requirements of the medium.
