Proofreading Symbols: A Guide to Standard Editorial Marks
In the world of professional editing and publishing, clear communication between the editor and the typesetter is essential. While digital tools have streamlined the process, standard proofreading symbols remain the universal language for requesting precise changes to a manuscript. Many of these marks are recognized by The Chicago Manual of Style, ensuring consistency across various publications.
These symbols allow editors to indicate deletions, insertions, and formatting changes without writing lengthy instructions. While some symbols correspond to specific Unicode codepoints—the unique numerical identifiers for every character in the Unicode Standard—others are specialized typographical marks used specifically for print correction.

Key Facts
- Proofreading symbols provide a shorthand for editors to communicate specific text changes.
- Many standard marks are documented in The Chicago Manual of Style.
- Some symbols have direct Unicode equivalents, while others are typographical approximations.
- Marks cover a range of functions, from basic deletions to complex spacing and punctuation adjustments.
Common Proofreading Symbols and Their Meanings
Editorial marks are generally categorized by the type of action they request. Whether you are adjusting the layout or correcting a typo, using the correct symbol prevents ambiguity during the production phase.
Text Deletion and Insertion
The most frequent edits involve removing unnecessary text or adding missing words. The Dele mark is used to signal that a character or word should be deleted. To add text, editors use the Caret (Unicode U+2038, 2041, or 2380), which points to the exact location where the new content should be inserted.
Paragraph and Spacing Adjustments
Managing the flow of text requires specific symbols for paragraphing and spacing. The Pilcrow (Unicode U+00B6), represented by the symbol ¶, indicates the start of a new paragraph. Conversely, a pilcrow followed by "no" (¶ no) instructs the editor to remove a paragraph break. For spacing, the hash symbol (#, Unicode U+0023) is used to insert a space, while the Close up mark (⁐, Unicode U+2050) is used to tie words together by eliminating an existing space.
Formatting and Punctuation
Precise punctuation is critical for professional writing. Editors use specific shorthand for dashes and stops: an underlined M (M̲) for an em dash, an underlined N (N̲) for an en dash, and a circle with a dot (☉) to insert a full stop. If a different punctuation mark is required, a circle (⚪︎) is used with the desired mark placed inside it.
Alignment and Positioning
Layout changes are handled with bracket-style symbols. To center text, brackets are placed around the target phrase (] [). To shift text horizontally, a single bracket is used: a right bracket (]) moves text to the right, and a left bracket ([) moves text to the left.

Frequently Asked Questions
What is a pilcrow used for in proofreading?
A pilcrow (¶) is used to indicate that a new paragraph should begin at that location. If the symbol is followed by "no," it means the existing paragraph break should be removed.
How do I indicate that a space should be removed between words?
To remove a space and tie two words together, use the Close up symbol (⁐, Unicode U+2050).
What is the difference between the M̲ and N̲ symbols?
The M̲ symbol is used to request the insertion of an em dash (a long dash), while the N̲ symbol is used for an en dash (a shorter dash).
How do I request a specific punctuation mark that doesn't have its own symbol?
You can use a circle (⚪︎) and place the specific punctuation mark you want inside the circle to signal its insertion.
Which style guide covers these symbols?
Most of these symbols can be found in The Chicago Manual of Style, which serves as a primary reference for professional editorial standards.
