What are proofreading symbols?

The basic proofreading symbols are abstract symbols used as shorthand by editors. Each symbol corresponds to a different action the writer should take in their next draft. For instance, they might use the pilcrow symbol (¶) to indicate making a new paragraph.

As you can imagine, proofreading someone else's writing can be a long and cumbersome process. Editors often find themselves requesting the same basic changes over and over. Rather than write out each one, they use the basic proofreading symbols to speed up the process.

Basic proofreading symbols

Delete (₰)

Delete symbol

The delete symbol (also called the Dele symbol) can be used over a single letter or an entire word. As the name implies, it tells the writer to delete whatever the symbol is cover.

How to make the delete symbol in Microsoft Word:

Strikethrough: Ctrl + D (opens Font dialog) → Select "Strikethrough".

Replace with (^)

Replace with symbol

The replace with symbol tells a writer to replace a word or sentence with a new piece of suggested text. The proofreader will write the new text above the replace with symbol.

How to make the replace with symbol in Microsoft Word:

Transpose (𝑡𝑟)

Transpose symbol

The transpose symbol means you should switch the order of two characters, words, or phrases. The symbol is often used when a writer mistakenly wrote a list of adjectives in the wrong order, like "tall very" instead of "very tall."
